Of the members of a student choir, 60% are boys. If there are 21 boys in the choir, how many members does the choir have in total?

Answer 1

35 members.

Learning percentages is easy once you get it down ;D

Answer 2

Suppose there are x number of members in all.

Now we are given that 60% of these are boys.

So number of members who are boys = 0.6x

We are also given that there are 21 boys in the choir.

So making an equation ,

$0.6x =21$

dividing both sides by 0.6,

x= 35

So there are total 35 members in the choir.
