Question

The ratio of boys to girls in a class is 4:5 what fraction of the class is boys and what fraction of the class is girls

Answer 1

First, let's start off with the information we already have. Since the ratio is 4 boys to 5 girls, there has to be a minimum of 9 students (4 being boys and 5 being girls).

9 will be the denominator of both of our fractions since the boys and girls are in the same class.

The fraction of boys in the class is 4/9 (since there are 4 boys to 5 girls in a class of 9, we would write 4 over 9) and the fraction of girls in the class is 5/9.

This is a simplified version of the fractions. If this is a multiple-answer question and 4/9 and 5/9 are not up there, try multiplying the fractions with different numbers and see what fractions will be correct. 

But either way, 4/9 and 5/9 are correct :)

Answer 2

Answer:

4/9 and 5/9

Step-by-step explanation:

It's simple really you add up the ratios 4+5=9

So 9 will be the amount you have so this will be the denominator.

This means the fraction of boys will be 4/9 and the fraction of girls will be 5/9.

I hope this helped :)
