You can put this solution on YOUR website! the ratio of boys to girls in Mr. Crofts gym class is 5:7.
How many girls will be there if there are 15 boys?
-----------------------
5:7 is the same as 5x:7x where x is any number except zero.
----------
# of boys = 5x = 15
x = 3
----
Ans:: # of girls = 7x = 7*3 = 21
