8 is what percent of 51.56 - 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 51.56 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 51.56, so we can write it down as 100%=51.56.
4. We know, that x% equals 8 of the output value, so we can write it down as x%=8.
5. Now we have two simple equations:
1) 100%=51.56
2) x%=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%=51.56/8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8 is what percent of 51.56

100%/x%=51.56/8
(100/x)*x=(51.56/8)*x       - we multiply both sides of the equation by x
100=6.445*x       - we divide both sides of the equation by (6.445) to get x
100/6.445=x
15.515903801396=x
x=15.515903801396

now we have:
8 is 15.515903801396% of 51.56
