Question

There are 20 girls in Mr. Pickle's class, If 30% of the students are girls, about how many boys are in his class?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

girls = 20

girls percentage = 30%

boys = ?

Step 02:

total students = x

20 girls ---------- 30 %

x ---------- 100%

30 * x = 20 * 100

x = 2000 / 30

x = 66.6

boys = 66.6 - 20 = 46.6

boys = 47

The answer is:

There are 47 boys. .
