Question

In a certain class the ratio of men to women is 3:5.
If the class has 24 people in it, how many are
women?

Answer 1

15 Explanation: let ratio be 3x and 5x. Total people= 24. We have 3x+5x=24. 8x=24 X=24. X=3. 5x= 5*3= 15

Answer 2

Answer:

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 $3:5$

In a class there are $24$ people.

Find:

To find the number of women in a class.

Solution:

Given that the ratio of men and women in a class is $3:5$

Let us assume the ratio be $3x$ and $5x$

Given the total no of people in a class is $24$

We have $3x + 5x = 24$

                      $8x = 24$

                       $x = 3$

Hence

Substituting $x = 3$

we get $3(3) = 9$

The number of women in a class is $5 (3) = 15$.
