Question

Brooke has to set up 70 chairs in equal rows for the class talent show. But, there is not room for more than 20 rows. What are the possible number of rows that Brooke could set up?

Answer 1

4 rows

70 divided by 20 is 3.5 but it's not possible to have 3.5 rows so to fit all the chairs you need 4 rows.
