256.5 is what percent of 325 - 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 325 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 325, so we can write it down as 100%=325.
4. We know, that x% equals 256.5 of the output value, so we can write it down as x%=256.5.
5. Now we have two simple equations:
1) 100%=325
2) x%=256.5
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%=325/256.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 256.5 is what percent of 325

100%/x%=325/256.5
(100/x)*x=(325/256.5)*x       - we multiply both sides of the equation by x
100=1.2670565302144*x       - we divide both sides of the equation by (1.2670565302144) to get x
100/1.2670565302144=x
78.923076923077=x
x=78.923076923077

now we have:
256.5 is 78.923076923077% of 325
