3.6 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 3.6 of the output value, so we can write it down as x%=3.6.
5. Now we have two simple equations:
1) 100%=13
2) x%=3.6
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%=13/3.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.6 is what percent of 13

100%/x%=13/3.6
(100/x)*x=(13/3.6)*x       - we multiply both sides of the equation by x
100=3.6111111111111*x       - we divide both sides of the equation by (3.6111111111111) to get x
100/3.6111111111111=x
27.692307692308=x
x=27.692307692308

now we have:
3.6 is 27.692307692308% of 13
