39.75 is what percent of 254.25 - 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 254.25 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 254.25, so we can write it down as 100%=254.25.
4. We know, that x% equals 39.75 of the output value, so we can write it down as x%=39.75.
5. Now we have two simple equations:
1) 100%=254.25
2) x%=39.75
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%=254.25/39.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.75 is what percent of 254.25

100%/x%=254.25/39.75
(100/x)*x=(254.25/39.75)*x       - we multiply both sides of the equation by x
100=6.3962264150943*x       - we divide both sides of the equation by (6.3962264150943) to get x
100/6.3962264150943=x
15.634218289086=x
x=15.634218289086

now we have:
39.75 is 15.634218289086% of 254.25
