Question

A) 18
B) 36
C) 27
D) 45

Answer 1

To find 25% of a number, set up a proportion and solve for the unknown variable.

Step-by-step explanation:

In order to find 25% of a certain number, we can set up the proportion:

9 is to x as 25 is to 100

To solve for x, we can cross-multiply and solve the resulting equation:

25x = 9 * 100

25x = 900

x = 900 / 25

x = 36

Therefore, 9 is 25% of 36.
