Question

55 percent of the students in a school are girls.Find the total number of students in the school if the number of boys is 180.

Answer 1

Answer:

The total number of students in the school is 400.

Step-by-step explanation:

It is provided that 55% of students are girls.

Then the proportion of boys is, 100 - 55 = 45%.

The number of boys is 180.

Then 45% of x = 180.

Compute the value of x as follows:

$45\%\times x=180\\0.45x=180\\x=\frac{180}{0.45}\\x=400$

Thus, the total number of students in the school is 400.
