15.75 is what percent of 125.75 - 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 125.75 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 125.75, so we can write it down as 100%=125.75.
4. We know, that x% equals 15.75 of the output value, so we can write it down as x%=15.75.
5. Now we have two simple equations:
1) 100%=125.75
2) x%=15.75
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%=125.75/15.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.75 is what percent of 125.75

100%/x%=125.75/15.75
(100/x)*x=(125.75/15.75)*x       - we multiply both sides of the equation by x
100=7.984126984127*x       - we divide both sides of the equation by (7.984126984127) to get x
100/7.984126984127=x
12.524850894632=x
x=12.524850894632

now we have:
15.75 is 12.524850894632% of 125.75
