81.25 is what percent of 163.75 - 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 163.75 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 163.75, so we can write it down as 100%=163.75.
4. We know, that x% equals 81.25 of the output value, so we can write it down as x%=81.25.
5. Now we have two simple equations:
1) 100%=163.75
2) x%=81.25
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%=163.75/81.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.25 is what percent of 163.75

100%/x%=163.75/81.25
(100/x)*x=(163.75/81.25)*x       - we multiply both sides of the equation by x
100=2.0153846153846*x       - we divide both sides of the equation by (2.0153846153846) to get x
100/2.0153846153846=x
49.618320610687=x
x=49.618320610687

now we have:
81.25 is 49.618320610687% of 163.75
