8.54 is what percent of 13.2 - 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 13.2 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 13.2, so we can write it down as 100%=13.2.
4. We know, that x% equals 8.54 of the output value, so we can write it down as x%=8.54.
5. Now we have two simple equations:
1) 100%=13.2
2) x%=8.54
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%=13.2/8.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.54 is what percent of 13.2

100%/x%=13.2/8.54
(100/x)*x=(13.2/8.54)*x       - we multiply both sides of the equation by x
100=1.5456674473068*x       - we divide both sides of the equation by (1.5456674473068) to get x
100/1.5456674473068=x
64.69696969697=x
x=64.69696969697

now we have:
8.54 is 64.69696969697% of 13.2
