13.72 is what percent of 6860 - 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 6860 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 6860, so we can write it down as 100%=6860.
4. We know, that x% equals 13.72 of the output value, so we can write it down as x%=13.72.
5. Now we have two simple equations:
1) 100%=6860
2) x%=13.72
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%=6860/13.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.72 is what percent of 6860

100%/x%=6860/13.72
(100/x)*x=(6860/13.72)*x       - we multiply both sides of the equation by x
100=500*x       - we divide both sides of the equation by (500) to get x
100/500=x
0.2=x
x=0.2

now we have:
13.72 is 0.2% of 6860
