8.68 is what percent of 10.72 - 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 10.72 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 10.72, so we can write it down as 100%=10.72.
4. We know, that x% equals 8.68 of the output value, so we can write it down as x%=8.68.
5. Now we have two simple equations:
1) 100%=10.72
2) x%=8.68
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%=10.72/8.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.68 is what percent of 10.72

100%/x%=10.72/8.68
(100/x)*x=(10.72/8.68)*x       - we multiply both sides of the equation by x
100=1.2350230414747*x       - we divide both sides of the equation by (1.2350230414747) to get x
100/1.2350230414747=x
80.970149253731=x
x=80.970149253731

now we have:
8.68 is 80.970149253731% of 10.72
