Question

In Ms.Perron's class, 75% of the students are boys.There are 18 boys in the class. What is the total students in Ms.Perron's class?

Answer 1

24.

Explanation:

75: 3/4

18 / 3 = 6

6 x 4 = 24

0.75 x 24 = 18

Answer 2

Explanation:

Let x be the total students.

75% of x = 18

(75/100) * x = 18

x = 18 * 100 / 75

= 18 * 4 / 3 ( giving by 25th table)

= 6 * 4 ( giving by 3rd table)

x = 24 students
