They must now have 8 boys. Agree?
to have 1/3 boys, after the 8
boys= 1/3 (32+x)
8+x= 1/3(32+x)
multiply bot sides by 3
24+3x=32+x
can you take it from here?
A club has 32 members only 1/4 are boys. How many more boys would they need to have at least 1/3 boys if no more girls are added?

Here's one way to figure it out.
We know there are 8 boys in the club.
We're looking for a number larger than 32 that is evenly divisible by 3. But 33 doesn't work because 8 + 1 isn't 1/3 of 33.
The next number is 36. Try that one.
I hope a math tutor can post a better method for solving this problem.

I believe it is 2 and 1/3
