9.6 is what percent of 12.69 - 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 12.69 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 12.69, so we can write it down as 100%=12.69.
4. We know, that x% equals 9.6 of the output value, so we can write it down as x%=9.6.
5. Now we have two simple equations:
1) 100%=12.69
2) x%=9.6
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%=12.69/9.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.6 is what percent of 12.69

100%/x%=12.69/9.6
(100/x)*x=(12.69/9.6)*x       - we multiply both sides of the equation by x
100=1.321875*x       - we divide both sides of the equation by (1.321875) to get x
100/1.321875=x
75.65011820331=x
x=75.65011820331

now we have:
9.6 is 75.65011820331% of 12.69
