721.5 is what percent of 7500 - 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 7500 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 7500, so we can write it down as 100%=7500.
4. We know, that x% equals 721.5 of the output value, so we can write it down as x%=721.5.
5. Now we have two simple equations:
1) 100%=7500
2) x%=721.5
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%=7500/721.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 721.5 is what percent of 7500

100%/x%=7500/721.5
(100/x)*x=(7500/721.5)*x       - we multiply both sides of the equation by x
100=10.39501039501*x       - we divide both sides of the equation by (10.39501039501) to get x
100/10.39501039501=x
9.62=x
x=9.62

now we have:
721.5 is 9.62% of 7500
