132.44 is what percent of 641.25 - 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 641.25 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 641.25, so we can write it down as 100%=641.25.
4. We know, that x% equals 132.44 of the output value, so we can write it down as x%=132.44.
5. Now we have two simple equations:
1) 100%=641.25
2) x%=132.44
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%=641.25/132.44
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 132.44 is what percent of 641.25

100%/x%=641.25/132.44
(100/x)*x=(641.25/132.44)*x       - we multiply both sides of the equation by x
100=4.8418151615826*x       - we divide both sides of the equation by (4.8418151615826) to get x
100/4.8418151615826=x
20.653411306043=x
x=20.653411306043

now we have:
132.44 is 20.653411306043% of 641.25
