256.5 is what percent of 3049.9 - 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 3049.9 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 3049.9, so we can write it down as 100%=3049.9.
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%=3049.9
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%=3049.9/256.5
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 3049.9

100%/x%=3049.9/256.5
(100/x)*x=(3049.9/256.5)*x       - we multiply both sides of the equation by x
100=11.89044834308*x       - we divide both sides of the equation by (11.89044834308) to get x
100/11.89044834308=x
8.4101118069445=x
x=8.4101118069445

now we have:
256.5 is 8.4101118069445% of 3049.9
