6.88 is what percent of 12.5 - 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 12.5 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 12.5, so we can write it down as 100%=12.5.
4. We know, that x% equals 6.88 of the output value, so we can write it down as x%=6.88.
5. Now we have two simple equations:
1) 100%=12.5
2) x%=6.88
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%=12.5/6.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.88 is what percent of 12.5

100%/x%=12.5/6.88
(100/x)*x=(12.5/6.88)*x       - we multiply both sides of the equation by x
100=1.8168604651163*x       - we divide both sides of the equation by (1.8168604651163) to get x
100/1.8168604651163=x
55.04=x
x=55.04

now we have:
6.88 is 55.04% of 12.5
