27.7 is what percent of 38 - 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 38 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 38, so we can write it down as 100%=38.
4. We know, that x% equals 27.7 of the output value, so we can write it down as x%=27.7.
5. Now we have two simple equations:
1) 100%=38
2) x%=27.7
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%=38/27.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.7 is what percent of 38

100%/x%=38/27.7
(100/x)*x=(38/27.7)*x       - we multiply both sides of the equation by x
100=1.3718411552347*x       - we divide both sides of the equation by (1.3718411552347) to get x
100/1.3718411552347=x
72.894736842105=x
x=72.894736842105

now we have:
27.7 is 72.894736842105% of 38
