25.5 is what percent of 38.5 - 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 38.5 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 38.5, so we can write it down as 100%=38.5.
4. We know, that x% equals 25.5 of the output value, so we can write it down as x%=25.5.
5. Now we have two simple equations:
1) 100%=38.5
2) x%=25.5
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%=38.5/25.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.5 is what percent of 38.5

100%/x%=38.5/25.5
(100/x)*x=(38.5/25.5)*x       - we multiply both sides of the equation by x
100=1.5098039215686*x       - we divide both sides of the equation by (1.5098039215686) to get x
100/1.5098039215686=x
66.233766233766=x
x=66.233766233766

now we have:
25.5 is 66.233766233766% of 38.5
