256.9 is what percent of 25.69 - 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 25.69 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 25.69, so we can write it down as 100%=25.69.
4. We know, that x% equals 256.9 of the output value, so we can write it down as x%=256.9.
5. Now we have two simple equations:
1) 100%=25.69
2) x%=256.9
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%=25.69/256.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 256.9 is what percent of 25.69

100%/x%=25.69/256.9
(100/x)*x=(25.69/256.9)*x       - we multiply both sides of the equation by x
100=0.1*x       - we divide both sides of the equation by (0.1) to get x
100/0.1=x
1000=x
x=1000

now we have:
256.9 is 1000% of 25.69
