Given:

The number of girls in the class = 20

To Find:

The ratio of the number of boys to the number of girls in the class

Solution:

The ratio of two quantities with the same units indicates the number of times one quantity contains the other.

It is expressed as x : y such that x and y have no common factor.

The ratio of the number of boys to the number of girls in the class = The number of boys in the class : The number of girls in the class
