13.36 is what percent of 684 - 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 684 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 684, so we can write it down as 100%=684.
4. We know, that x% equals 13.36 of the output value, so we can write it down as x%=13.36.
5. Now we have two simple equations:
1) 100%=684
2) x%=13.36
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%=684/13.36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.36 is what percent of 684

100%/x%=684/13.36
(100/x)*x=(684/13.36)*x       - we multiply both sides of the equation by x
100=51.197604790419*x       - we divide both sides of the equation by (51.197604790419) to get x
100/51.197604790419=x
1.953216374269=x
x=1.953216374269

now we have:
13.36 is 1.953216374269% of 684
