What is 8400 percent of 400000000 - 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 400000000 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 400000000 is 100%, so we can write it down as 400000000=100%.
4. We know, that x is 8400% of the output value, so we can write it down as x=8400%.
5. Now we have two simple equations:
1) 400000000=100%
2) x=8400%
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:
400000000/x=100%/8400%
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 8400% of 400000000

400000000/x=100/8400
(400000000/x)*x=(100/8400)*x       - we multiply both sides of the equation by x
400000000=0.011904761904762*x       - we divide both sides of the equation by (0.011904761904762) to get x
400000000/0.011904761904762=x
33600000000=x
x=33600000000

now we have:
8400% of 400000000=33600000000
