79.8 is what percent of 81.875 - 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 81.875 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 81.875, so we can write it down as 100%=81.875.
4. We know, that x% equals 79.8 of the output value, so we can write it down as x%=79.8.
5. Now we have two simple equations:
1) 100%=81.875
2) x%=79.8
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%=81.875/79.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79.8 is what percent of 81.875

100%/x%=81.875/79.8
(100/x)*x=(81.875/79.8)*x       - we multiply both sides of the equation by x
100=1.0260025062657*x       - we divide both sides of the equation by (1.0260025062657) to get x
100/1.0260025062657=x
97.465648854962=x
x=97.465648854962

now we have:
79.8 is 97.465648854962% of 81.875
