<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

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>
