13.18 is what percent of 212.5 - 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 212.5 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 212.5, so we can write it down as 100%=212.5.
4. We know, that x% equals 13.18 of the output value, so we can write it down as x%=13.18.
5. Now we have two simple equations:
1) 100%=212.5
2) x%=13.18
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%=212.5/13.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.18 is what percent of 212.5

100%/x%=212.5/13.18
(100/x)*x=(212.5/13.18)*x       - we multiply both sides of the equation by x
100=16.122913505311*x       - we divide both sides of the equation by (16.122913505311) to get x
100/16.122913505311=x
6.2023529411765=x
x=6.2023529411765

now we have:
13.18 is 6.2023529411765% of 212.5
