38.89 is what percent of 40.54 - 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 40.54 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 40.54, so we can write it down as 100%=40.54.
4. We know, that x% equals 38.89 of the output value, so we can write it down as x%=38.89.
5. Now we have two simple equations:
1) 100%=40.54
2) x%=38.89
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%=40.54/38.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.89 is what percent of 40.54

100%/x%=40.54/38.89
(100/x)*x=(40.54/38.89)*x       - we multiply both sides of the equation by x
100=1.0424273592183*x       - we divide both sides of the equation by (1.0424273592183) to get x
100/1.0424273592183=x
95.92994573261=x
x=95.92994573261

now we have:
38.89 is 95.92994573261% of 40.54
