627.66 is what percent of 4140 - 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 4140 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 4140, so we can write it down as 100%=4140.
4. We know, that x% equals 627.66 of the output value, so we can write it down as x%=627.66.
5. Now we have two simple equations:
1) 100%=4140
2) x%=627.66
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%=4140/627.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 627.66 is what percent of 4140

100%/x%=4140/627.66
(100/x)*x=(4140/627.66)*x       - we multiply both sides of the equation by x
100=6.5959277315744*x       - we divide both sides of the equation by (6.5959277315744) to get x
100/6.5959277315744=x
15.160869565217=x
x=15.160869565217

now we have:
627.66 is 15.160869565217% of 4140
