Explain how you would find 90% of 120.

Answer 1

Our trick here is to think that a fraction in %

land is the same as the correspondent in "number" land; so we can write:
100%
90%
= 120x
Where X is the correspondent of 90% in numbers.
Rearranging: x = 120⋅
90% 100% =108

Answer 2

If 120 = 100% then how much of it is 90%?

To find out you will have to multiply 90 with 120 and then divide what you get with 100.

90 x 120 = 10800

10800/100 = 108

so 90% of 120 is 108.

Hope this helped :)
