10.5 is what percent of 125.5 - 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 125.5 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 125.5, so we can write it down as 100%=125.5.
4. We know, that x% equals 10.5 of the output value, so we can write it down as x%=10.5.
5. Now we have two simple equations:
1) 100%=125.5
2) x%=10.5
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%=125.5/10.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.5 is what percent of 125.5

100%/x%=125.5/10.5
(100/x)*x=(125.5/10.5)*x       - we multiply both sides of the equation by x
100=11.952380952381*x       - we divide both sides of the equation by (11.952380952381) to get x
100/11.952380952381=x
8.3665338645418=x
x=8.3665338645418

now we have:
10.5 is 8.3665338645418% of 125.5
