#80%#

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%#
