11.05 is what percent of 13 - 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 13 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 13, so we can write it down as 100%=13.
4. We know, that x% equals 11.05 of the output value, so we can write it down as x%=11.05.
5. Now we have two simple equations:
1) 100%=13
2) x%=11.05
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%=13/11.05
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.05 is what percent of 13

100%/x%=13/11.05
(100/x)*x=(13/11.05)*x       - we multiply both sides of the equation by x
100=1.1764705882353*x       - we divide both sides of the equation by (1.1764705882353) to get x
100/1.1764705882353=x
85=x
x=85

now we have:
11.05 is 85% of 13
