8.8 is what percent of 30.9 - 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 30.9 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 30.9, so we can write it down as 100%=30.9.
4. We know, that x% equals 8.8 of the output value, so we can write it down as x%=8.8.
5. Now we have two simple equations:
1) 100%=30.9
2) x%=8.8
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%=30.9/8.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.8 is what percent of 30.9

100%/x%=30.9/8.8
(100/x)*x=(30.9/8.8)*x       - we multiply both sides of the equation by x
100=3.5113636363636*x       - we divide both sides of the equation by (3.5113636363636) to get x
100/3.5113636363636=x
28.478964401295=x
x=28.478964401295

now we have:
8.8 is 28.478964401295% of 30.9
