Evaluate the following

42 percent (%) of 80 is what number?

Set up our equation

Let's call our missing number x.

Expressing this in terms of an equation:
we get: 42% * 80 = x

Build percentage

x  =  42 * 80
  100

x  =  3360
  100

Since our fraction is not reduced, we need to calculate a greatest common factor

From that lesson, we have a GCF of 20

Dividing numerator and denominator by our 20, we get 168/5

Final Answer

42 percent (%) of 80 is 33.6 or 168/5
