6.72 is what percent of 30.72 - 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 30.72 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 30.72, so we can write it down as 100%=30.72.
4. We know, that x% equals 6.72 of the output value, so we can write it down as x%=6.72.
5. Now we have two simple equations:
1) 100%=30.72
2) x%=6.72
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%=30.72/6.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.72 is what percent of 30.72

100%/x%=30.72/6.72
(100/x)*x=(30.72/6.72)*x       - we multiply both sides of the equation by x
100=4.5714285714286*x       - we divide both sides of the equation by (4.5714285714286) to get x
100/4.5714285714286=x
21.875=x
x=21.875

now we have:
6.72 is 21.875% of 30.72
