128.1 is what percent of 8.75 - 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 8.75 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 8.75, so we can write it down as 100%=8.75.
4. We know, that x% equals 128.1 of the output value, so we can write it down as x%=128.1.
5. Now we have two simple equations:
1) 100%=8.75
2) x%=128.1
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%=8.75/128.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.1 is what percent of 8.75

100%/x%=8.75/128.1
(100/x)*x=(8.75/128.1)*x       - we multiply both sides of the equation by x
100=0.068306010929*x       - we divide both sides of the equation by (0.068306010929) to get x
100/0.068306010929=x
1464=x
x=1464

now we have:
128.1 is 1464% of 8.75
