Question

: In Ms. Perron’s class, 40% of the students are boys. There are 10 boys in the class. What is the total number of students in Ms. Perron’s class?

Answer 1

Total number of students in Ms. Perron’s class is 25

Solution:

In Ms. Perron’s class, 40% of the students are boys

There are 10 boys in the class

Let "x" be the total number of students in Perron class

From given,

40 % of total students are boys

Therefore,

40 % of x = 10

$\frac{40}{100} \times x = 10\\\\40x = 1000\\\\x = 25$

Thus total number of students in Ms. Perron’s class is 25
