657.79 is what percent of 10000 - 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 10000 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 10000, so we can write it down as 100%=10000.
4. We know, that x% equals 657.79 of the output value, so we can write it down as x%=657.79.
5. Now we have two simple equations:
1) 100%=10000
2) x%=657.79
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%=10000/657.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 657.79 is what percent of 10000

100%/x%=10000/657.79
(100/x)*x=(10000/657.79)*x       - we multiply both sides of the equation by x
100=15.2024202253*x       - we divide both sides of the equation by (15.2024202253) to get x
100/15.2024202253=x
6.5779=x
x=6.5779

now we have:
657.79 is 6.5779% of 10000
