What is 65000000 percent of 400 - 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 400 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 400 is 100%, so we can write it down as 400=100%.
4. We know, that x is 65000000% of the output value, so we can write it down as x=65000000%.
5. Now we have two simple equations:
1) 400=100%
2) x=65000000%
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:
400/x=100%/65000000%
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 65000000% of 400

400/x=100/65000000
(400/x)*x=(100/65000000)*x       - we multiply both sides of the equation by x
400=1.5384615384615E-6*x       - we divide both sides of the equation by (1.5384615384615E-6) to get x
400/1.5384615384615E-6=x
260000000=x
x=260000000

now we have:
65000000% of 400=260000000
