What is the 15% of 90

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    

100/90     × p/100
