523 is what percent of 572 - 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 572 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 572, so we can write it down as 100%=572.
4. We know, that x% equals 523 of the output value, so we can write it down as x%=523.
5. Now we have two simple equations:
1) 100%=572
2) x%=523
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%=572/523
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 523 is what percent of 572

100%/x%=572/523
(100/x)*x=(572/523)*x       - we multiply both sides of the equation by x
100=1.093690248566*x       - we divide both sides of the equation by (1.093690248566) to get x
100/1.093690248566=x
91.433566433566=x
x=91.433566433566

now we have:
523 is 91.433566433566% of 572
