8.75 is what percent of 121.7 - 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 121.7 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 121.7, so we can write it down as 100%=121.7.
4. We know, that x% equals 8.75 of the output value, so we can write it down as x%=8.75.
5. Now we have two simple equations:
1) 100%=121.7
2) x%=8.75
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%=121.7/8.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.75 is what percent of 121.7

100%/x%=121.7/8.75
(100/x)*x=(121.7/8.75)*x       - we multiply both sides of the equation by x
100=13.908571428571*x       - we divide both sides of the equation by (13.908571428571) to get x
100/13.908571428571=x
7.189811010682=x
x=7.189811010682

now we have:
8.75 is 7.189811010682% of 121.7
