13.83 is what percent of 66.37 - 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 66.37 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 66.37, so we can write it down as 100%=66.37.
4. We know, that x% equals 13.83 of the output value, so we can write it down as x%=13.83.
5. Now we have two simple equations:
1) 100%=66.37
2) x%=13.83
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%=66.37/13.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.83 is what percent of 66.37

100%/x%=66.37/13.83
(100/x)*x=(66.37/13.83)*x       - we multiply both sides of the equation by x
100=4.7989877078814*x       - we divide both sides of the equation by (4.7989877078814) to get x
100/4.7989877078814=x
20.837727889107=x
x=20.837727889107

now we have:
13.83 is 20.837727889107% of 66.37
