Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to find how many boys are there in the school.
• So, to find that, we have to first multiply the fraction by the number of students in the school.
• Then, after finding the number of girls, we have to subtract it from the number of boys in the school.

Given :

• Girls = 1/3
• No of students in School = 1200

To find :

• number of boys

Solution :

↦ Let's find out the number of girls.

$\sf \Rightarrow \dfrac{1}{3} \times 1200$

$\sf \Rightarrow \dfrac{1 \times 1200}{3}$

$\sf \Rightarrow \dfrac{1200}{3}$

$\sf \Rightarrow 400$

• Therefore, 400 girls are there in the school.

↦ Now, let's find the number of boys.

→ 1200 - 400

→ 800

• Therefore, 800 boys are there in the school.
