79.78 is what percent of 125 - 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 125 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 125, so we can write it down as 100%=125.
4. We know, that x% equals 79.78 of the output value, so we can write it down as x%=79.78.
5. Now we have two simple equations:
1) 100%=125
2) x%=79.78
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%=125/79.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79.78 is what percent of 125

100%/x%=125/79.78
(100/x)*x=(125/79.78)*x       - we multiply both sides of the equation by x
100=1.566808723991*x       - we divide both sides of the equation by (1.566808723991) to get x
100/1.566808723991=x
63.824=x
x=63.824

now we have:
79.78 is 63.824% of 125
