The ratio of boys to girls in a class is 5:4 there are 36 students in the class how many students are girls

First add up the total parts in the ratio.

5 + 4 = 9

Now we need to know the value of each part

36 / 9 = 4

The girls has total of 4 parts, therefore we can just multiply the number of parts by the amount in each part

4 x 4 = 16

So there r 16 girls in the class
