Answer:
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 percent's 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 x 90 =15
