128.65 is what percent of 175.1 - 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 175.1 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 175.1, so we can write it down as 100%=175.1.
4. We know, that x% equals 128.65 of the output value, so we can write it down as x%=128.65.
5. Now we have two simple equations:
1) 100%=175.1
2) x%=128.65
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%=175.1/128.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.65 is what percent of 175.1

100%/x%=175.1/128.65
(100/x)*x=(175.1/128.65)*x       - we multiply both sides of the equation by x
100=1.3610571317528*x       - we divide both sides of the equation by (1.3610571317528) to get x
100/1.3610571317528=x
73.472301541976=x
x=73.472301541976

now we have:
128.65 is 73.472301541976% of 175.1
