12.71 is what percent of 161 - 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 161 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 161, so we can write it down as 100%=161.
4. We know, that x% equals 12.71 of the output value, so we can write it down as x%=12.71.
5. Now we have two simple equations:
1) 100%=161
2) x%=12.71
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%=161/12.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.71 is what percent of 161

100%/x%=161/12.71
(100/x)*x=(161/12.71)*x       - we multiply both sides of the equation by x
100=12.667191188041*x       - we divide both sides of the equation by (12.667191188041) to get x
100/12.667191188041=x
7.8944099378882=x
x=7.8944099378882

now we have:
12.71 is 7.8944099378882% of 161
