12.61 is what percent of 80.75 - 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 80.75 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 80.75, so we can write it down as 100%=80.75.
4. We know, that x% equals 12.61 of the output value, so we can write it down as x%=12.61.
5. Now we have two simple equations:
1) 100%=80.75
2) x%=12.61
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%=80.75/12.61
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.61 is what percent of 80.75

100%/x%=80.75/12.61
(100/x)*x=(80.75/12.61)*x       - we multiply both sides of the equation by x
100=6.4036478984933*x       - we divide both sides of the equation by (6.4036478984933) to get x
100/6.4036478984933=x
15.616099071207=x
x=15.616099071207

now we have:
12.61 is 15.616099071207% of 80.75
