Step-by-step explanation:

Concept:

A ratio in mathematics shows how many times one number is contained in another.

A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations.

A ratio can therefore be thought of as an ordered pair of integers, a fraction with the first number in the numerator and the second in the denominator, or as the value represented by this fraction.

Given:

In a certain class the ratio of men to women is In a class there are people.

Find:

To find the number of women in a class.

Solution:

Given that the ratio of men and women in a class is Let us assume the ratio be and Given the total no of people in a class is We have   Hence

Substituting we get The number of women in a class is .
