Question

There are 20 students in a class.

12 of the students are girls.
Find the ratio of the number of girls to the number of boys.
Give your ratio in the form n : 1.

Answer 1

1.5:1

Explanation:

the original answer is 12:8, so you have to simplify it down. you can get it down to 3:2 with whole numbers, but to get it down to a ratio with one, you'll have to divide each number by 2 because the bottom number is 2, so the final answer would be 1.5:1
