13.5 is what percent of 65.2 - 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 65.2 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 65.2, so we can write it down as 100%=65.2.
4. We know, that x% equals 13.5 of the output value, so we can write it down as x%=13.5.
5. Now we have two simple equations:
1) 100%=65.2
2) x%=13.5
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%=65.2/13.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.5 is what percent of 65.2

100%/x%=65.2/13.5
(100/x)*x=(65.2/13.5)*x       - we multiply both sides of the equation by x
100=4.8296296296296*x       - we divide both sides of the equation by (4.8296296296296) to get x
100/4.8296296296296=x
20.705521472393=x
x=20.705521472393

now we have:
13.5 is 20.705521472393% of 65.2
