No, that would be of all the student...we need to find how many boys total.

mathmale · Answer

If 45% of the students are girls, then (100-45)% are boys.  What is (100-45)% ?
Convert that to a decimal fraction.

Here is what I did:

45% * 80 = 36 = # of girls.

80-36= 44 = # of boys. 

25% * 44 = 11 = # of unemployed boys

44-11 = 33 = # of employed boys.
