Answer:
20 boys
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.
