Question

In a community survey, 13/20 of the residents claim to recycle. If there are 720 residents, how many residents claim to recycle?

Answer 1

468

Explanation:

make a proportion:

13/20 = x/720

20x?=720

20x36=720

whatever you do to the bottom you do to the top

13x36=468

468/720 residents claim to recycle
