Question

The ratio of boys to girls in a class is 5:4. There are 36 students in the class. How many students are boys?

Answer 1

Answer:

20 boys

Step-by-step explanation:

Let's look at the ratio:

Boys : Girls

5 : 4

In this ratio, how many students are in the class?

To figure this out, add the number of boys and girls.

5 + 4 = 9

There are 9 students in the class.

We need to find the number of boys is there were 36 students in the class.

To do this, find the relationship between 9 and 36 by dividing.

36/9 = 4

Now we know that we need to multiply both sides of the ratio by 4 to find the number of boys in a class of 36 students.

Multiply:

Boys : Girls

5 : 4

x4  x4

20 : 16

Therefore, there are 20 boys in the class.

Answer 2

The answer is 20 boys!

Step-by-step explanation:

If you multiply the ratio by 4 it will equal 20:16, which is equal to 36.
