Pie graphs represent data in a circle. Here, you can learn how to read or use pie graphs or circle charts.

## Step by step guide to solve Pie Graph problems

- A Pie Chart is a circle chart divided into sectors, each sector represents the relative size of each value.
- To solve problems related to pie graphs, first, categorize your Data, find the Total, and find the value for each category or sector.

### Example 1:

A library has \(670\) books that include Mathematics, Physics, Chemistry, English, and History. Use the following graph to answer the question. What is the number of Mathematics books?

**Solution:**

Number of total books \(=670 \)

Percent of Mathematics books \(=30\%=0.30\)

Then: \(0.30×670=201\)

### Example 2:

A library has \(840\) books that include Mathematics, Physics, Chemistry, English, and History. Use following graph to answer question. What is the number of Mathematics books?

**Solution:**

Number of total books \(=840 \)

Percent of Mathematics books \(=30\%=0.30\)

Then: \(0.30×840=252\)

## Exercises

### Answer the following questions based on the Pie graph.

**Jason spent $2,500 last month. **

- How much did Jason spend on his car last month?
- How much did Jason spend on foods last month?
- How much did Jason spend on his rent last month?
- What fraction is Jason’s expenses for his bills and Car out of his total expenses last month?
