To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 1580 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 1580 is 100%, so we can write it down as 1580=100%.
4. We know, that x is 25% of the output value, so we can write it down as x=25%.
5. Now we have two simple equations:
1) 1580=100%
2) x=25%
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:
1580/x=100%/25%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

1580=4*x - we divide both sides of the equation by (4) to get x
1580/4=x
395=x
x=395

now we have:
25% of 1580=395
