What's 48 decreased 25%

In this question, we will assume that 48 represents 100 %

What is 25% of 100%?

we need to divide the two, so:

25/100 = 0.25

We know that after a decrease of 25% the original number 48 has to be less in the final analysis.

we now multiply 0.25 by 48, so:

0.25 * 48 = 12

Therefore 48 has decreased by 12. What has remained?

we subtract the numbers.

48 - 12 = 36

Therefore 48 decreased by 25% will be 36.
