144.4 is what percent of 129.12 - 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 129.12 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 129.12, so we can write it down as 100%=129.12.
4. We know, that x% equals 144.4 of the output value, so we can write it down as x%=144.4.
5. Now we have two simple equations:
1) 100%=129.12
2) x%=144.4
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%=129.12/144.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 144.4 is what percent of 129.12

100%/x%=129.12/144.4
(100/x)*x=(129.12/144.4)*x       - we multiply both sides of the equation by x
100=0.89418282548476*x       - we divide both sides of the equation by (0.89418282548476) to get x
100/0.89418282548476=x
111.83395291202=x
x=111.83395291202

now we have:
144.4 is 111.83395291202% of 129.12
