Answer 2

3.33% of 360 cm is 12 cm. The number of boys in the school is 480.

Explanation:

We can assume the number 360 is 100%

If 100% equals 360, then 100% = 360.

We know that x% equals 12, so we can write it down as x% = 12.

Therefore, $\frac{100}{x} =\frac{360}{12}$

1200 = 360x

x = $\frac{360}{1200}$

x = 3.33%

Given: A school has 800 students.

40% of the students are girls.

Number of boys = ?

Let the number of boys in 100% = 100% - 40% ⇒ 60%

Therefore, 60% of 800 students = $\frac{60}{100}\times 800$

= 480

The number of boys in the school is 480.
