11.5 is what percent of 13.4 - 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 13.4 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 13.4, so we can write it down as 100%=13.4.
4. We know, that x% equals 11.5 of the output value, so we can write it down as x%=11.5.
5. Now we have two simple equations:
1) 100%=13.4
2) x%=11.5
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%=13.4/11.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.5 is what percent of 13.4

100%/x%=13.4/11.5
(100/x)*x=(13.4/11.5)*x       - we multiply both sides of the equation by x
100=1.1652173913043*x       - we divide both sides of the equation by (1.1652173913043) to get x
100/1.1652173913043=x
85.820895522388=x
x=85.820895522388

now we have:
11.5 is 85.820895522388% of 13.4
