1.1 is what percent of 12.8 - 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 12.8 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 12.8, so we can write it down as 100%=12.8.
4. We know, that x% equals 1.1 of the output value, so we can write it down as x%=1.1.
5. Now we have two simple equations:
1) 100%=12.8
2) x%=1.1
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%=12.8/1.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.1 is what percent of 12.8

100%/x%=12.8/1.1
(100/x)*x=(12.8/1.1)*x       - we multiply both sides of the equation by x
100=11.636363636364*x       - we divide both sides of the equation by (11.636363636364) to get x
100/11.636363636364=x
8.59375=x
x=8.59375

now we have:
1.1 is 8.59375% of 12.8
