Bar Charts and Bar Graphs Explained!

Complete Guide: Bar Charts and Bar Graphs

Key Question: What is a bar chart? How do you read and how do you create a bar chart or bar graph?

Bar Chart Example

Bar Chart Example

Welcome to this free step-by-step guide to bar charts and bar graphs. This guide will teach you how to create a bar chart from a data table and how to read a bar chart and draw conclusions from the data it represents.

Below you will find several bar graph examples that will help you to learn how to understand bar graphs.

Note that this lesson will use bar graph and bar chart interchangeably, as both terms mean the same thing.

Also, this free guide includes an animated video lesson and a free practice worksheet with a full answer key.

What is a Bar Chart? What is a Bar Graph?

A bar chart, also referred to as a bar graph, is a diagram that can be used to compare and contrast values in relation to each other.

Bar graphs include rectangular bars that are in proportion to the values that they represent.

Now, let’s take a look at our first example:

Bar Graph Example 01

How to Create a Bar Graph

Create a bar graph that represents the data chart for a student survey of favorite types of drinks.

The first step to making a bar graph is to give the bar graph a title. For this example, you can title the graph Favorite Types of Drinks.

Snip20210401_54.png
 

The next step is to label the vertical and horizontal axes.

For the vertical axis, you must choose numerical units that match the data. Since all of the numbers in the table are single-digit values, you can make the vertical axis values go from zero to ten. Note that the first value on any bar graph (located in the bottom -left corner) will always be zero.

On the horizontal axis, you will include a label for each data item. In this example, each data item is a type of drink: Milk, Soda, Water, Juice, and Tea.

Snip20210401_57.png
 

Now you are ready to construct your bars!

Start with the first data value, which is Milk, by constructing a bar over the Milk label that starts at zero and rises up to the number 1, which corresponds with the value for Milk in the data table.

Next, repeat this process for the other data items on the chart: Soda-3, Water-6, Juice-7, and Tea-5:

Snip20210401_60.png
 

And now you made a bar graph that represents the data table.

Bar Graph Example 02

How to Read a Bar Graph

Unlike the last example where you had to create your own bar graph, let’s get some practice reading bar graphs and drawing conclusions.

Complete the data chart and draw 3 conclusions from the bar graph below:

Snip20210401_61.png

To complete the data chart for this bar graph, simply see which value each items bar sits at.

For example, the bar graph shows the number of pounds of radishes sold was 50 (because the vertical bar over radishes stops at 50).

Furthermore, notice that the bar graph shows the number of pounds of sweet potatoes sold is midway between 70 and 80, so we can conclude that the total number of pounds sold was 75.

Continue this process to complete the data table as follows:

Snip20210401_62.png

The last step is to use the bar graph to draw some conclusions from the data.

For example:

  • Carrots are the most sold vegetable (the bar for carrots was the highest)

  • Cabbage is the least sold vegetable (the bar for cabbage was the lowest)

  • 15 more pounds of sweet potatoes sold than onions sold (the bar for sweet potatoes is 15 taller than the bar for onions)

Can you draw 3 more conclusions from the bar graph on your own?

Dividing Fractions in 3 Easy Steps: Your Complete Guide

Complete Guide: Dividing Fractions

Key Question: How do you divide fractions by fractions and fractions with whole numbers?

Learn to divide fractions using 3 easy steps.

Learn to divide fractions using 3 easy steps.

Welcome to this free step-by-step guide to dividing fractions. This guide will teach you how to use a simple three-step method called Keep-Change-Flip to easily divide fractions by fractions (and fractions by whole numbers as well).

Below you will find several examples of how to divide fractions using the Keep-Change-Flip method along with an explanation of why the method works for any math problem that involves dividing fractions. Additionally, this free guide includes an animated video lesson and a free practice worksheet with answers!

Are you ready to get started?

Dividing Fractions: Multiplication Review

Before you learn how to divide fractions using the Keep-Change-Flip method, you need to make sure that you understand how to multiply fractions together (which is even easier than dividing!).

Since multiplying fractions is typically taught before dividing fractions, you may already know how to multiply two fractions together. If this is the case, you can skip ahead to the next section.

However, if you want a quick review of how to multiply fractions, here is the rule:

Multiplying Fractions Rule: Whenever multiplying fractions together, multiply the numerators together, then multiply the denominators together as follows…

Snip20200320_8.png
 

For example, 3/4 x 1/2 can be solved as follows:

Snip20200320_10.png

Dividing Fractions Examples!

Now that you know how to multiply fractions, you are ready to learn how to divide fractions using the simple 3-step Keep-Change-Flip method.

Let’s start with a simple example

Dividing Fractions Example 1

Example 1: What is 1/2 ÷ 1/4 ?

Snip20210317_4.png
 

To solve this example (and any problem where you have to divide fractions, we are going to use the Keep-Change-Flip method)

Snip20210317_8.png
 

Where:

1.) KEEP = Keep the first fraction as is and just leave it alone.

2.) CHANGE = Change the division sign to a multiplication sign.

3.) FLIP = Flip the second fraction (swap the numerator and the denominator)

These steps can be applied to example 1 as follows:

Snip20210317_5.png
Snip20210317_6.png
Snip20210317_7.png
 

Again, after applying Keep-Change-Flip, we have transformed the original problem of 1/2 ÷ 1/4 as follows:

Snip20210317_3.png
 

Now you can solve the problem by multiplying the fractions together and simplifying if necessary:

Snip20210317_9.png
Notice that 4/2 can be simplified.

Notice that 4/2 can be simplified.

Snip20210317_11.png
 

The final answer is 2, and we can conclude that the answer to the original problem is…

Final Answer: 1/2 ÷ 1/4 = 2

Snip20210317_12.png
 

Why Does This Answer Mean?

In example 1, we concluded that 1/2 ÷ 1/4 = 2. But what does this actually mean?

If we think about 1/2 ÷ 1/4 in the form of a question: How many 1/4s are in 1/2?

And then if we visualize 1/4 and 1/2, we can clearly see that there are 2 1/4s in 1/2, which is why the final answer is 2.

Snip20210317_13.png
 

Fraction Divided by Fraction: Example 2

Example 2: What is 2/9 ÷ 1/3 ?

Snip20210317_15.png
 

Just like example 01, you can solve this problem by using the keep change flip method as follows:

1.) Keep the first fraction 2/9 as is.

2.) Change the division sign to multiplication.

3.) Flip the second fraction to turn 1/3 into 3/1

Snip20210317_16.png
Snip20210317_17.png
 

Next, perform 2/9 x 3/1 as follows and simplify the answer if you can:

Snip20210317_18.png
Snip20210317_19.png
Snip20210317_20.png
 

In this example, 6/9 is not the final answer, since it can be reduced to 2/3

The final answer is 2/3, and we can conclude that the answer to the original problem is…

Final Answer: 2/9 ÷ 1/3 = 2/3

Snip20210317_21.png
 

Dividing Fractions by Whole Numbers: Example 3

What if you have to divide a fraction with a whole number? It turns out the process is exactly the same as the previous examples!

Example 03: What is 5 ÷ 2/3 ?

Snip20210317_22.png
 

Notice that, in this example, you are dividing a fraction with a whole number. But it is actually very easy to convert a whole number into a fraction. All that you have to do is rewrite the number as fraction where the number itself is in the numerator and the denominator is 1.

For example, 5 can be rewritten as 5/1 and this rule applies for any whole number!

Snip20210317_23.png
 

Now that you have rewritten the whole number as a fraction, you can use the Keep-Change-Flip method to solve the problem.

1.) Keep the first fraction 5/1 as is.

2.) Change the division sign to multiplication.

3.) Flip the second fraction to turn 2/3 into 3/2

Snip20210317_24.png
 

Finally, multiply the fractions together and simplify if possible to find the final answer as follows:

Snip20210317_25.png
15/2 can not be simplified, however, it can be expressed as 7 & 1/2

15/2 can not be simplified, however, it can be expressed as 7 & 1/2

Snip20210317_27.png
 

In this example, the answer can be expressed as 15/2 or as 7 & 1/2.

And you can conclude that the answer to the original problem is…

Final Answer: 5 ÷ 2/3 = 15/2 or 7&1/2

How to Use a Protractor: Your Complete Guide

Complete Guide: How to Use a Protractor

Key Question: How can I use a protractor to measure angles?

Learn how to solve these kinds of problems.

Learn how to solve these kinds of problems.

Welcome to this free lesson guide where you will learn how to read a protractor and how to use it to measure angles.

This complete guide on how to use a protractor includes several examples, an animated video mini-lesson, and a free worksheet and answer key.

Let’s get started!

How to Use a Protractor: Quick Review

Before we learn how to use the protractor tool to measure angles, let’s do a super quick review of angle notation (understanding this important skill will make learning how to use a protractor much easier).

Angle Notation: In geometry, an angle is denoted by the ∠ symbol and includes 3 consecutive letters which represent the three points that form the angle. Note that the middle letter denotes the vertex point of the angle.

For example, notice how in the diagram below that both angles ∠ABD and ∠CBD have point B as their vertex, but have different measures?

In this example, ∠ABD=120 and ∠CBD=60. But what happens when the angle measures are not included on the diagram? How can you find the measure of the angles in these kinds of situations?

This is where the protractor tool comes in!

How to Use a Protractor

Now that you know understand angle notation, you are ready to learn how to use the protractor tool to find the measure of an angle.

Example: Use a protractor to find the measure of ∠MLN in the diagram below.

Snip20210223_4.png
 

First, make sure that you correctly identify the angle in question. ∠MLN is the angle formed by points M, L, and N with a vertex at point L. Notice that the ∠MLN is now colored in the diagram below. If you find having the angle colored helpful, you can use markers or highlighters whenever you are using a protractor to measure angles on paper.

Snip20210223_5.png

Quick Note: Before moving forward, identify the Center Marker on your protractor.

 
Center.jpg
 

The next step is to line up the center marker of the protractor with the vertex point of the angle (point L in this example) as follows:

Snip20210223_6.png

Make sure that the bottom ray of the angle (segment LN in this example) is aligned with the bottom of the protractor as shown in the diagram.

How to Read a Protractor

60 or 120?

60 or 120?

Now that you have your protractor in position, the last step is to use it to identify the angle measure.

Remember that we are trying to find the measure of ∠MLN. In order to do this, we must identify where the top ray of the angle (segment LM in this example) intersects with the protractor and then read the measurements.

Notice that where segment LM crosses the protractor, there are two values: 60 and 120.

Since ∠MLN is an acute angle (less than 90 degrees), you know that it can not equal 120 degrees.

Therefore, the measure of ∠MLN must be 60 degrees.

Snip20210223_8.png

How to Read a Protractor: More Examples

Below are a few more examples of how to read a protractor.

Example A: ∠EFT = 100

Notice that the angle in question is obtuse (>90 degrees)

Notice that the angle in question is obtuse (>90 degrees)

Example B: ∠GFT = 80

Notice that the angle in question is acute  (<90 degrees)

Notice that the angle in question is acute (<90 degrees)

Example C: ∠RQS = 35

Notice that the angle in question is acute  (&lt;90 degrees)

Notice that the angle in question is acute (<90 degrees)

Example D: ∠PQS = 151

Notice that the angle in question is obtuse  (&gt;90 degrees)

Notice that the angle in question is obtuse (>90 degrees)

Example E: Right Angles

Ex05.jpg
Example06.jpg
 

In Example D, notice that both angles in question ∠WYZ and ∠WYX are right angles, thus they are neither acute or obtuse and both have an angle measure of 90 degrees.

You probably didn’t need a protractor to identify that ∠WYZ and ∠WYX were right angles, but this example shows you how a protractor can always help you to find the measure of a give angle.

Pretty cool, right?
