13.82 is what percent of 67.2 - 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 67.2 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 67.2, so we can write it down as 100%=67.2.
4. We know, that x% equals 13.82 of the output value, so we can write it down as x%=13.82.
5. Now we have two simple equations:
1) 100%=67.2
2) x%=13.82
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%=67.2/13.82
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.82 is what percent of 67.2

100%/x%=67.2/13.82
(100/x)*x=(67.2/13.82)*x       - we multiply both sides of the equation by x
100=4.862518089725*x       - we divide both sides of the equation by (4.862518089725) to get x
100/4.862518089725=x
20.565476190476=x
x=20.565476190476

now we have:
13.82 is 20.565476190476% of 67.2
