16.28 is what percent of 20.72 - 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 20.72 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 20.72, so we can write it down as 100%=20.72.
4. We know, that x% equals 16.28 of the output value, so we can write it down as x%=16.28.
5. Now we have two simple equations:
1) 100%=20.72
2) x%=16.28
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%=20.72/16.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.28 is what percent of 20.72

100%/x%=20.72/16.28
(100/x)*x=(20.72/16.28)*x       - we multiply both sides of the equation by x
100=1.2727272727273*x       - we divide both sides of the equation by (1.2727272727273) to get x
100/1.2727272727273=x
78.571428571429=x
x=78.571428571429

now we have:
16.28 is 78.571428571429% of 20.72
