938.6 is what percent of 7220 - 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 7220 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 7220, so we can write it down as 100%=7220.
4. We know, that x% equals 938.6 of the output value, so we can write it down as x%=938.6.
5. Now we have two simple equations:
1) 100%=7220
2) x%=938.6
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%=7220/938.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 938.6 is what percent of 7220

100%/x%=7220/938.6
(100/x)*x=(7220/938.6)*x       - we multiply both sides of the equation by x
100=7.6923076923077*x       - we divide both sides of the equation by (7.6923076923077) to get x
100/7.6923076923077=x
13=x
x=13

now we have:
938.6 is 13% of 7220
