37.81 is what percent of 72.31 - 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 72.31 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 72.31, so we can write it down as 100%=72.31.
4. We know, that x% equals 37.81 of the output value, so we can write it down as x%=37.81.
5. Now we have two simple equations:
1) 100%=72.31
2) x%=37.81
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%=72.31/37.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37.81 is what percent of 72.31

100%/x%=72.31/37.81
(100/x)*x=(72.31/37.81)*x       - we multiply both sides of the equation by x
100=1.91245702195*x       - we divide both sides of the equation by (1.91245702195) to get x
100/1.91245702195=x
52.2887567418=x
x=52.2887567418

now we have:
37.81 is 52.2887567418% of 72.31
