25.6 is what percent of 64.8 - 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 64.8 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 64.8, so we can write it down as 100%=64.8.
4. We know, that x% equals 25.6 of the output value, so we can write it down as x%=25.6.
5. Now we have two simple equations:
1) 100%=64.8
2) x%=25.6
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%=64.8/25.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.6 is what percent of 64.8

100%/x%=64.8/25.6
(100/x)*x=(64.8/25.6)*x       - we multiply both sides of the equation by x
100=2.53125*x       - we divide both sides of the equation by (2.53125) to get x
100/2.53125=x
39.506172839506=x
x=39.506172839506

now we have:
25.6 is 39.506172839506% of 64.8
