688.72 is what percent of 25500 - 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 25500 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 25500, so we can write it down as 100%=25500.
4. We know, that x% equals 688.72 of the output value, so we can write it down as x%=688.72.
5. Now we have two simple equations:
1) 100%=25500
2) x%=688.72
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%=25500/688.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 688.72 is what percent of 25500

100%/x%=25500/688.72
(100/x)*x=(25500/688.72)*x       - we multiply both sides of the equation by x
100=37.02520617958*x       - we divide both sides of the equation by (37.02520617958) to get x
100/37.02520617958=x
2.700862745098=x
x=2.700862745098

now we have:
688.72 is 2.700862745098% of 25500
