Complete Question:

There are 450 learners in a rural school. The ratio of the number of boys to girls is 7:8. How Many boys and how many girls are there in the school?

Answer:

I. Boys, B = 210 learners.

II. Girls, G = 240 learners.

Step-by-step explanation:

Let the number of boys be B.

Let the number of girls be G.

Given the following data;

Total number of learners = 450 learners.

Ratio of B to G = 7:8

Ratio = 7 + 8 = 15

To find the value of B;

`B = \frac {7}{15} * 450`

`B = \frac {3150}{15}`

Boys, B = 210 learners.

To find the value of G;

`G = \frac {8}{15} * 450`

`G = \frac {3600}{15}`

Girls, G = 240 learners.
