What is 25 percent of 4109 - 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 4109 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 4109 is 100%, so we can write it down as 4109=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) 4109=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:
4109/x=100%/25%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 25% of 4109

4109/x=100/25
(4109/x)*x=(100/25)*x       - we multiply both sides of the equation by x
4109=4*x       - we divide both sides of the equation by (4) to get x
4109/4=x
1027.25=x
x=1027.25

now we have:
25% of 4109=1027.25
