13.38 is what percent of 83 - 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 83 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 83, so we can write it down as 100%=83.
4. We know, that x% equals 13.38 of the output value, so we can write it down as x%=13.38.
5. Now we have two simple equations:
1) 100%=83
2) x%=13.38
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%=83/13.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.38 is what percent of 83

100%/x%=83/13.38
(100/x)*x=(83/13.38)*x       - we multiply both sides of the equation by x
100=6.203288490284*x       - we divide both sides of the equation by (6.203288490284) to get x
100/6.203288490284=x
16.120481927711=x
x=16.120481927711

now we have:
13.38 is 16.120481927711% of 83
