129.8 is what percent of 327.2 - 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 327.2 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 327.2, so we can write it down as 100%=327.2.
4. We know, that x% equals 129.8 of the output value, so we can write it down as x%=129.8.
5. Now we have two simple equations:
1) 100%=327.2
2) x%=129.8
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%=327.2/129.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 129.8 is what percent of 327.2

100%/x%=327.2/129.8
(100/x)*x=(327.2/129.8)*x       - we multiply both sides of the equation by x
100=2.5208012326656*x       - we divide both sides of the equation by (2.5208012326656) to get x
100/2.5208012326656=x
39.669926650367=x
x=39.669926650367

now we have:
129.8 is 39.669926650367% of 327.2
