198.79 is what percent of 1002 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 1002 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 1002, so we can write it down as 100%=1002.
4. We know, that x% equals 198.79 of the output value, so we can write it down as x%=198.79.
5. Now we have two simple equations:
1) 100%=1002
2) x%=198.79
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=1002/198.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 198.79 is what percent of 1002

100%/x%=1002/198.79
(100/x)*x=(1002/198.79)*x       - we multiply both sides of the equation by x
100=5.040494994718*x       - we divide both sides of the equation by (5.040494994718) to get x
100/5.040494994718=x
19.839321357285=x
x=19.839321357285

now we have:
198.79 is 19.839321357285% of 1002
