0.38 is what percent of 171 - 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 171 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 171, so we can write it down as 100%=171.
4. We know, that x% equals 0.38 of the output value, so we can write it down as x%=0.38.
5. Now we have two simple equations:
1) 100%=171
2) x%=0.38
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%=171/0.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.38 is what percent of 171

100%/x%=171/0.38
(100/x)*x=(171/0.38)*x       - we multiply both sides of the equation by x
100=450*x       - we divide both sides of the equation by (450) to get x
100/450=x
0.22222222222222=x
x=0.22222222222222

now we have:
0.38 is 0.22222222222222% of 171
