What is 25 percent of 12087 - 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 12087 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 12087 is 100%, so we can write it down as 12087=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) 12087=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:
12087/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 12087

12087/x=100/25
(12087/x)*x=(100/25)*x       - we multiply both sides of the equation by x
12087=4*x       - we divide both sides of the equation by (4) to get x
12087/4=x
3021.75=x
x=3021.75

now we have:
25% of 12087=3021.75
