    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.
