What is 4000 percent of 12405 - 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 12405 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 12405 is 100%, so we can write it down as 12405=100%.
4. We know, that x is 4000% of the output value, so we can write it down as x=4000%.
5. Now we have two simple equations:
1) 12405=100%
2) x=4000%
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:
12405/x=100%/4000%
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 4000% of 12405

12405/x=100/4000
(12405/x)*x=(100/4000)*x       - we multiply both sides of the equation by x
12405=0.025*x       - we divide both sides of the equation by (0.025) to get x
12405/0.025=x
496200=x
x=496200

now we have:
4000% of 12405=496200
