What is 40000 percent of 312000000 - 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 312000000 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 312000000 is 100%, so we can write it down as 312000000=100%.
4. We know, that x is 40000% of the output value, so we can write it down as x=40000%.
5. Now we have two simple equations:
1) 312000000=100%
2) x=40000%
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:
312000000/x=100%/40000%
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 40000% of 312000000

312000000/x=100/40000
(312000000/x)*x=(100/40000)*x       - we multiply both sides of the equation by x
312000000=0.0025*x       - we divide both sides of the equation by (0.0025) to get x
312000000/0.0025=x
124800000000=x
x=124800000000

now we have:
40000% of 312000000=124800000000
