there are three boys for every five girls in the choir. Which of the following numbers is closest to the percentage of boys in the chamber choir 
32, 34, 36, 38, or 40?
----------------------------
3:5 is the same as 3x:5x where 3x is the number of boys out of 8x.

Percentage = 3x/8x = 3/8 = 37.5%
Ans: 38
