Question

A group of 23 adults and 45 children are attending a play. Each row in the theater can seat 9 people.

What is the least number of rows needed to seat the group?

Answer 1

At least 8 rows

Explanation:

45 divided by 9 is 5. That is 5 rows

9x3= 27 and there are 23 adults. So that is 3 rows

5+3=8

8 rows in total.
