10.9 is what percent of 34.8 - 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 34.8 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 34.8, so we can write it down as 100%=34.8.
4. We know, that x% equals 10.9 of the output value, so we can write it down as x%=10.9.
5. Now we have two simple equations:
1) 100%=34.8
2) x%=10.9
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%=34.8/10.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.9 is what percent of 34.8

100%/x%=34.8/10.9
(100/x)*x=(34.8/10.9)*x       - we multiply both sides of the equation by x
100=3.1926605504587*x       - we divide both sides of the equation by (3.1926605504587) to get x
100/3.1926605504587=x
31.32183908046=x
x=31.32183908046

now we have:
10.9 is 31.32183908046% of 34.8
