521.25 is what percent of 72000 - 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 72000 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 72000, so we can write it down as 100%=72000.
4. We know, that x% equals 521.25 of the output value, so we can write it down as x%=521.25.
5. Now we have two simple equations:
1) 100%=72000
2) x%=521.25
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%=72000/521.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 521.25 is what percent of 72000

100%/x%=72000/521.25
(100/x)*x=(72000/521.25)*x       - we multiply both sides of the equation by x
100=138.12949640288*x       - we divide both sides of the equation by (138.12949640288) to get x
100/138.12949640288=x
0.72395833333333=x
x=0.72395833333333

now we have:
521.25 is 0.72395833333333% of 72000
