136.8 is what percent of 323.1 - 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 323.1 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 323.1, so we can write it down as 100%=323.1.
4. We know, that x% equals 136.8 of the output value, so we can write it down as x%=136.8.
5. Now we have two simple equations:
1) 100%=323.1
2) x%=136.8
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%=323.1/136.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 136.8 is what percent of 323.1

100%/x%=323.1/136.8
(100/x)*x=(323.1/136.8)*x       - we multiply both sides of the equation by x
100=2.3618421052632*x       - we divide both sides of the equation by (2.3618421052632) to get x
100/2.3618421052632=x
42.339832869081=x
x=42.339832869081

now we have:
136.8 is 42.339832869081% of 323.1
