Question

in a school 5/7 of the students are boys if there are 300girls find the number of boys in the school
​

Answer 1

Answer:

750 boys

Step-by-step explanation:

Let total students be 1

Boys = 5/7

Girls = 2/7

5:2 ratio

Let 2x is girls, 5x is boys.

sum of ratio 7

$\frac{2x}{7} = 300 \\ 2x = 2100 \\ x = 1050$

So boys = 5x

$\frac{5x}{7 } \\ \frac{5(1050)}{7} \\ = 750$
