Katarina [22]

Answer:

<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of books in the children's section at the local library = 500

Ratio 2:3 for picture books and chapter books

2. How many chapter books are in the section?

We will use the Rule of Three Simple for answering this question, this way:

Chapter books       Total books

3                                  5

x                                 500

x * 5 = 500 * 3

5x = 1,500

x = 1,500/5

x = 300

<u>There are 300 chapter books and 200 picture books in the children's section at the local library.</u>
