Question

The chairs in a school were arranged in 15 rows with 28 chairs in each row if these chairs were rearranged into rows of 20 how many rows of chairs would there be

Answer 1

Answer: 21 rows

Explanation:

First find out the number of chairs that are currently in the school.

= 15 rows * 28 chairs

= 420 chairs

If 420 chairs were to be arranged in rows of 20, the number of rows would therefore be:

= 420 / 20 per row

= 21 rows
