51.5 is what percent of 108 - 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 108 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 108, so we can write it down as 100%=108.
4. We know, that x% equals 51.5 of the output value, so we can write it down as x%=51.5.
5. Now we have two simple equations:
1) 100%=108
2) x%=51.5
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%=108/51.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51.5 is what percent of 108

100%/x%=108/51.5
(100/x)*x=(108/51.5)*x       - we multiply both sides of the equation by x
100=2.0970873786408*x       - we divide both sides of the equation by (2.0970873786408) to get x
100/2.0970873786408=x
47.685185185185=x
x=47.685185185185

now we have:
51.5 is 47.685185185185% of 108
