129.27 is what percent of 287.37 - 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 287.37 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 287.37, so we can write it down as 100%=287.37.
4. We know, that x% equals 129.27 of the output value, so we can write it down as x%=129.27.
5. Now we have two simple equations:
1) 100%=287.37
2) x%=129.27
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%=287.37/129.27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 129.27 is what percent of 287.37

100%/x%=287.37/129.27
(100/x)*x=(287.37/129.27)*x       - we multiply both sides of the equation by x
100=2.2230215827338*x       - we divide both sides of the equation by (2.2230215827338) to get x
100/2.2230215827338=x
44.983818770227=x
x=44.983818770227

now we have:
