If the ratio of girls to boys in a class is 4:3 and there are 9 boys in the class, How many students are in the class?

Answer 1

If the ratio is 4 (girls) to 3 (boys) then 4/7 are girls and 3/7 are boys

Then 3/7 (x) = 9 or x = 63/3 = 21 is the total number of students

So, if 9 are boys, then girls = 21-9 = 12
