51.15 is what percent of 68.2 - 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 68.2 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 68.2, so we can write it down as 100%=68.2.
4. We know, that x% equals 51.15 of the output value, so we can write it down as x%=51.15.
5. Now we have two simple equations:
1) 100%=68.2
2) x%=51.15
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%=68.2/51.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51.15 is what percent of 68.2

100%/x%=68.2/51.15
(100/x)*x=(68.2/51.15)*x       - we multiply both sides of the equation by x
100=1.33333333333*x       - we divide both sides of the equation by (1.33333333333) to get x
100/1.33333333333=x
75=x
x=75

now we have:
51.15 is 75% of 68.2
