73.5 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 73.5 of the output value, so we can write it down as x%=73.5.
5. Now we have two simple equations:
1) 100%=531
2) x%=73.5
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%=531/73.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 73.5 is what percent of 531

100%/x%=531/73.5
(100/x)*x=(531/73.5)*x       - we multiply both sides of the equation by x
100=7.2244897959184*x       - we divide both sides of the equation by (7.2244897959184) to get x
100/7.2244897959184=x
13.841807909605=x
x=13.841807909605

now we have:
73.5 is 13.841807909605% of 531
