31.7 is what percent of 58.1 - 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 58.1 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 58.1, so we can write it down as 100%=58.1.
4. We know, that x% equals 31.7 of the output value, so we can write it down as x%=31.7.
5. Now we have two simple equations:
1) 100%=58.1
2) x%=31.7
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%=58.1/31.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.7 is what percent of 58.1

100%/x%=58.1/31.7
(100/x)*x=(58.1/31.7)*x       - we multiply both sides of the equation by x
100=1.8328075709779*x       - we divide both sides of the equation by (1.8328075709779) to get x
100/1.8328075709779=x
54.561101549053=x
x=54.561101549053

now we have:
31.7 is 54.561101549053% of 58.1
