13.94 is what percent of 20.7 - 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 20.7 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 20.7, so we can write it down as 100%=20.7.
4. We know, that x% equals 13.94 of the output value, so we can write it down as x%=13.94.
5. Now we have two simple equations:
1) 100%=20.7
2) x%=13.94
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%=20.7/13.94
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.94 is what percent of 20.7

100%/x%=20.7/13.94
(100/x)*x=(20.7/13.94)*x       - we multiply both sides of the equation by x
100=1.4849354375897*x       - we divide both sides of the equation by (1.4849354375897) to get x
100/1.4849354375897=x
67.342995169082=x
x=67.342995169082

now we have:
13.94 is 67.342995169082% of 20.7
