37.1 is what percent of 338.9 - 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 338.9 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 338.9, so we can write it down as 100%=338.9.
4. We know, that x% equals 37.1 of the output value, so we can write it down as x%=37.1.
5. Now we have two simple equations:
1) 100%=338.9
2) x%=37.1
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%=338.9/37.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37.1 is what percent of 338.9

100%/x%=338.9/37.1
(100/x)*x=(338.9/37.1)*x       - we multiply both sides of the equation by x
100=9.1347708894879*x       - we divide both sides of the equation by (9.1347708894879) to get x
100/9.1347708894879=x
10.947182059605=x
x=10.947182059605

now we have:
37.1 is 10.947182059605% of 338.9
