13 is what percent of 94.5 - 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 94.5 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 94.5, so we can write it down as 100%=94.5.
4. We know, that x% equals 13 of the output value, so we can write it down as x%=13.
5. Now we have two simple equations:
1) 100%=94.5
2) x%=13
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%=94.5/13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13 is what percent of 94.5

100%/x%=94.5/13
(100/x)*x=(94.5/13)*x       - we multiply both sides of the equation by x
100=7.2692307692308*x       - we divide both sides of the equation by (7.2692307692308) to get x
100/7.2692307692308=x
13.756613756614=x
x=13.756613756614

now we have:
13 is 13.756613756614% of 94.5
