51.98 is what percent of 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 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 8, so we can write it down as 100%=8.
4. We know, that x% equals 51.98 of the output value, so we can write it down as x%=51.98.
5. Now we have two simple equations:
1) 100%=8
2) x%=51.98
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%=8/51.98
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51.98 is what percent of 8

100%/x%=8/51.98
(100/x)*x=(8/51.98)*x       - we multiply both sides of the equation by x
100=0.15390534821085*x       - we divide both sides of the equation by (0.15390534821085) to get x
100/0.15390534821085=x
649.75=x
x=649.75

now we have:
51.98 is 649.75% of 8
