77.8 is what percent of 95 - 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 95 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 95, so we can write it down as 100%=95.
4. We know, that x% equals 77.8 of the output value, so we can write it down as x%=77.8.
5. Now we have two simple equations:
1) 100%=95
2) x%=77.8
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%=95/77.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77.8 is what percent of 95

100%/x%=95/77.8
(100/x)*x=(95/77.8)*x       - we multiply both sides of the equation by x
100=1.2210796915167*x       - we divide both sides of the equation by (1.2210796915167) to get x
100/1.2210796915167=x
81.894736842105=x
x=81.894736842105

now we have:
77.8 is 81.894736842105% of 95
