Answer:
15 is
16.7
%
of 90
Explanation:
First, lets call the percent we are looking for "p".
"Percent" or "%" means "out of 100" or "per 100", Therefore p% can be written as
p
100
.
When dealing with percents the word "of" means "times" or "to multiply".
Putting this altogether we can write this equation and solve for
p
while keeping the equation balanced:
p
100
×
90
=
15
100
90

p
100

90

rounded to the nearest tenth.
