What is 400000 percent of 31 - 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 31 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 31 is 100%, so we can write it down as 31=100%.
4. We know, that x is 400000% of the output value, so we can write it down as x=400000%.
5. Now we have two simple equations:
1) 31=100%
2) x=400000%
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:
31/x=100%/400000%
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 400000% of 31

31/x=100/400000
(31/x)*x=(100/400000)*x       - we multiply both sides of the equation by x
31=0.00025*x       - we divide both sides of the equation by (0.00025) to get x
31/0.00025=x
124000=x
x=124000

now we have:
400000% of 31=124000
