Question

There are four more girls than boys in Ms. Raub's class of 28 students. What is the ratio of number of girls to the number of boys in her class?

Answer 1

so there are x girls and x-4 boys and together they make 28:

x+x-4=28
2x-4=28
2x=32
x=16

so there are 16 girls and 12 boys.

the ratio is then 16:12, or we can simplify (by dividing both sides by 4): 4:3

so the best answer is 4:3.
