13.2 is what percent of 142.86 - 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 142.86 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 142.86, so we can write it down as 100%=142.86.
4. We know, that x% equals 13.2 of the output value, so we can write it down as x%=13.2.
5. Now we have two simple equations:
1) 100%=142.86
2) x%=13.2
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%=142.86/13.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.2 is what percent of 142.86

100%/x%=142.86/13.2
(100/x)*x=(142.86/13.2)*x       - we multiply both sides of the equation by x
100=10.822727272727*x       - we divide both sides of the equation by (10.822727272727) to get x
100/10.822727272727=x
9.2398152036959=x
x=9.2398152036959

now we have:
13.2 is 9.2398152036959% of 142.86
