27.71 is what percent of 172 - 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 172 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 172, so we can write it down as 100%=172.
4. We know, that x% equals 27.71 of the output value, so we can write it down as x%=27.71.
5. Now we have two simple equations:
1) 100%=172
2) x%=27.71
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%=172/27.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.71 is what percent of 172

100%/x%=172/27.71
(100/x)*x=(172/27.71)*x       - we multiply both sides of the equation by x
100=6.2071454348611*x       - we divide both sides of the equation by (6.2071454348611) to get x
100/6.2071454348611=x
16.110465116279=x
x=16.110465116279

now we have:
27.71 is 16.110465116279% of 172
