250.8 is what percent of 317 - 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 317 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 317, so we can write it down as 100%=317.
4. We know, that x% equals 250.8 of the output value, so we can write it down as x%=250.8.
5. Now we have two simple equations:
1) 100%=317
2) x%=250.8
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%=317/250.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 250.8 is what percent of 317

100%/x%=317/250.8
(100/x)*x=(317/250.8)*x       - we multiply both sides of the equation by x
100=1.2639553429027*x       - we divide both sides of the equation by (1.2639553429027) to get x
100/1.2639553429027=x
79.116719242902=x
x=79.116719242902

now we have:
250.8 is 79.116719242902% of 317
