42 percent (%) of 80 is what number?

Let's call our missing number x.
Expressing this in terms of an equation, we get: 42% * 80 = x

Since a percentage is just the percent number divided by 100, we have:
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
x = 33.6 or 168/5

Now we know that 42 percent (%) of 80 is 33.6 or 168/5.
