1.28 is what percent of 110 - 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 110 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 110, so we can write it down as 100%=110.
4. We know, that x% equals 1.28 of the output value, so we can write it down as x%=1.28.
5. Now we have two simple equations:
1) 100%=110
2) x%=1.28
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%=110/1.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.28 is what percent of 110

100%/x%=110/1.28
(100/x)*x=(110/1.28)*x       - we multiply both sides of the equation by x
100=85.9375*x       - we divide both sides of the equation by (85.9375) to get x
100/85.9375=x
1.1636363636364=x
x=1.1636363636364

now we have:
1.28 is 1.1636363636364% of 110
