5.28 is what percent of 17.28 - 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 17.28 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 17.28, so we can write it down as 100%=17.28.
4. We know, that x% equals 5.28 of the output value, so we can write it down as x%=5.28.
5. Now we have two simple equations:
1) 100%=17.28
2) x%=5.28
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%=17.28/5.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.28 is what percent of 17.28

100%/x%=17.28/5.28
(100/x)*x=(17.28/5.28)*x       - we multiply both sides of the equation by x
100=3.2727272727273*x       - we divide both sides of the equation by (3.2727272727273) to get x
100/3.2727272727273=x
30.555555555556=x
x=30.555555555556

now we have:
5.28 is 30.555555555556% of 17.28
