How to calculate 15 percent of 80?

Percent formula 15 percent of 80

Step 1

The output value is 80 in this case. The unknown value is represented by y

Step 2

The output value can be written in the form of an equation as

(y / 80 ) = ( 15 /100) 

By solving the equation, we get

y = 0.15 x 80

y = 12
