79.2 is what percent of 200 - 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 200 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 200, so we can write it down as 100%=200.
4. We know, that x% equals 79.2 of the output value, so we can write it down as x%=79.2.
5. Now we have two simple equations:
1) 100%=200
2) x%=79.2
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%=200/79.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79.2 is what percent of 200

100%/x%=200/79.2
(100/x)*x=(200/79.2)*x       - we multiply both sides of the equation by x
100=2.5252525252525*x       - we divide both sides of the equation by (2.5252525252525) to get x
100/2.5252525252525=x
39.6=x
x=39.6

now we have:
79.2 is 39.6% of 200
