13.4 is what percent of 47.5 - 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 47.5 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 47.5, so we can write it down as 100%=47.5.
4. We know, that x% equals 13.4 of the output value, so we can write it down as x%=13.4.
5. Now we have two simple equations:
1) 100%=47.5
2) x%=13.4
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%=47.5/13.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.4 is what percent of 47.5

100%/x%=47.5/13.4
(100/x)*x=(47.5/13.4)*x       - we multiply both sides of the equation by x
100=3.544776119403*x       - we divide both sides of the equation by (3.544776119403) to get x
100/3.544776119403=x
28.210526315789=x
x=28.210526315789

now we have:
13.4 is 28.210526315789% of 47.5
