# Question 79028

Mar 2, 2017

80%

#### Explanation:

This question might be easier to understand if it was asked as
'What percentage is 72 out of 90"?

(Like a score on a test)

To find a percentage: " " "fraction" xx 100%

Note that 100% = 100/100 = 1

Multiplying by 1 does not change a value, just what it looks like.

72/90 xx 100%

= (0.8 xx 100)%

= 80%#
