19.71 is what percent of 13.61 - 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 13.61 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 13.61, so we can write it down as 100%=13.61.
4. We know, that x% equals 19.71 of the output value, so we can write it down as x%=19.71.
5. Now we have two simple equations:
1) 100%=13.61
2) x%=19.71
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%=13.61/19.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.71 is what percent of 13.61

100%/x%=13.61/19.71
(100/x)*x=(13.61/19.71)*x       - we multiply both sides of the equation by x
100=0.69051243023846*x       - we divide both sides of the equation by (0.69051243023846) to get x
100/0.69051243023846=x
144.81998530492=x
x=144.81998530492

now we have:
19.71 is 144.81998530492% of 13.61
