Evaluate the following
20 percent (%) of 50 is what number?
Set up our equation
Let's call our missing number x.
Expressing this in terms of an equation:
we get: 20% * 50 = x
Build percentage
| x = | 20 * 50 |
| 100 |
| x = | 1000 |
| 100 |
Since our fraction is not reduced, we need to calculate a greatest common factor
From that lesson, we have a GCF of 100
Dividing numerator and denominator by our 100, we get 10/1
Final Answer
20 percent (%) of 50 is 10 or 10/1
