Question:

The ratio of boys to girls in a class is 5:3. There are 32 students in the class. How many students are girls?

Answer:

The number of girls is 12.

Given:

The ratio of boys to girls in a class is 5:3.

There are 32 students in the class.

To find:

The number of girls.

Explanation:

Let, the common multiple of the ratio be ,'n'.

Hence,

The number of boys = (5×n)

                                    = 5n

The number of girls = (3×n)

                                 = 3n

∴ According to the problem:

5n+3n = 32

⇒ 8n = 32

⇒ n = (32÷8)

⇒ n = 4

∴ The number of girls = (4×3)

                                   = 12

∴ Among the students the number of girls is 12.
