Pie Graph – 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: \(0.30×670=201\)

Pie Graph – Example 2:

A library has \(840\) 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 \(=840 \)
Percent of Mathematics books \(=30\%=0.30\)
Then: \(0.30×840=252\)
