How to calculate 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
80 = 100%
In the same way, the unknown value can be written in the form of an equation as
y = 15%
Step 3
Divide both equations is written as
80 = 100%
y = 15%
( 80 % ) / ( y % ) = 100 / 15
Step 4
Reciprocal of both sides of the equation can be written as
(y / 80 ) = ( 15 /100)
By solving the equation, we get
y = 0.15 x 80
y = 12
