664.5 is what percent of 758 - 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 758 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 758, so we can write it down as 100%=758.
4. We know, that x% equals 664.5 of the output value, so we can write it down as x%=664.5.
5. Now we have two simple equations:
1) 100%=758
2) x%=664.5
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%=758/664.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 664.5 is what percent of 758

100%/x%=758/664.5
(100/x)*x=(758/664.5)*x       - we multiply both sides of the equation by x
100=1.1407072987208*x       - we divide both sides of the equation by (1.1407072987208) to get x
100/1.1407072987208=x
87.664907651715=x
x=87.664907651715

now we have:
664.5 is 87.664907651715% of 758
