51.19 is what percent of 57.7 - 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 57.7 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 57.7, so we can write it down as 100%=57.7.
4. We know, that x% equals 51.19 of the output value, so we can write it down as x%=51.19.
5. Now we have two simple equations:
1) 100%=57.7
2) x%=51.19
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%=57.7/51.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51.19 is what percent of 57.7

100%/x%=57.7/51.19
(100/x)*x=(57.7/51.19)*x       - we multiply both sides of the equation by x
100=1.1271732760305*x       - we divide both sides of the equation by (1.1271732760305) to get x
100/1.1271732760305=x
88.717504332756=x
x=88.717504332756

now we have:
51.19 is 88.717504332756% of 57.7
