122.88 is what percent of 151 - 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 151 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 151, so we can write it down as 100%=151.
4. We know, that x% equals 122.88 of the output value, so we can write it down as x%=122.88.
5. Now we have two simple equations:
1) 100%=151
2) x%=122.88
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%=151/122.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 122.88 is what percent of 151

100%/x%=151/122.88
(100/x)*x=(151/122.88)*x       - we multiply both sides of the equation by x
100=1.2288411458333*x       - we divide both sides of the equation by (1.2288411458333) to get x
100/1.2288411458333=x
81.377483443709=x
x=81.377483443709

now we have:
122.88 is 81.377483443709% of 151
