521.17 is what percent of 653.36 - 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 653.36 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 653.36, so we can write it down as 100%=653.36.
4. We know, that x% equals 521.17 of the output value, so we can write it down as x%=521.17.
5. Now we have two simple equations:
1) 100%=653.36
2) x%=521.17
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%=653.36/521.17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 521.17 is what percent of 653.36

100%/x%=653.36/521.17
(100/x)*x=(653.36/521.17)*x       - we multiply both sides of the equation by x
100=1.2536408465568*x       - we divide both sides of the equation by (1.2536408465568) to get x
100/1.2536408465568=x
79.767662544386=x
x=79.767662544386

now we have:
