146.4 is what percent of 128.9 - 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 128.9 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 128.9, so we can write it down as 100%=128.9.
4. We know, that x% equals 146.4 of the output value, so we can write it down as x%=146.4.
5. Now we have two simple equations:
1) 100%=128.9
2) x%=146.4
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%=128.9/146.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 146.4 is what percent of 128.9

100%/x%=128.9/146.4
(100/x)*x=(128.9/146.4)*x       - we multiply both sides of the equation by x
100=0.88046448087432*x       - we divide both sides of the equation by (0.88046448087432) to get x
100/0.88046448087432=x
113.57641582622=x
x=113.57641582622

now we have:
146.4 is 113.57641582622% of 128.9
