108.12 is what percent of 159 - 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 159 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 159, so we can write it down as 100%=159.
4. We know, that x% equals 108.12 of the output value, so we can write it down as x%=108.12.
5. Now we have two simple equations:
1) 100%=159
2) x%=108.12
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%=159/108.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 108.12 is what percent of 159

100%/x%=159/108.12
(100/x)*x=(159/108.12)*x       - we multiply both sides of the equation by x
100=1.4705882352941*x       - we divide both sides of the equation by (1.4705882352941) to get x
100/1.4705882352941=x
68=x
x=68

now we have:
108.12 is 68% of 159
