What is 12.69 percent of 331.85 - 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 331.85 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 331.85 is 100%, so we can write it down as 331.85=100%.
4. We know, that x is 12.69% of the output value, so we can write it down as x=12.69%.
5. Now we have two simple equations:
1) 331.85=100%
2) x=12.69%
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:
331.85/x=100%/12.69%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 12.69% of 331.85

331.85/x=100/12.69
(331.85/x)*x=(100/12.69)*x       - we multiply both sides of the equation by x
331.85=7.8802206461781*x       - we divide both sides of the equation by (7.8802206461781) to get x
331.85/7.8802206461781=x
42.111765=x
x=42.111765

now we have:
12.69% of 331.85=42.111765
