37 is what percent of 531 - 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 531 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 531, so we can write it down as 100%=531.
4. We know, that x% equals 37 of the output value, so we can write it down as x%=37.
5. Now we have two simple equations:
1) 100%=531
2) x%=37
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%=531/37
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37 is what percent of 531

100%/x%=531/37
(100/x)*x=(531/37)*x       - we multiply both sides of the equation by x
100=14.351351351351*x       - we divide both sides of the equation by (14.351351351351) to get x
100/14.351351351351=x
6.9679849340866=x
x=6.9679849340866

now we have:
37 is 6.9679849340866% of 531
