What is 0.78125 percent of 64000 - 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 64000 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 64000 is 100%, so we can write it down as 64000=100%.
4. We know, that x is 0.78125% of the output value, so we can write it down as x=0.78125%.
5. Now we have two simple equations:
1) 64000=100%
2) x=0.78125%
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:
64000/x=100%/0.78125%
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 0.78125% of 64000

64000/x=100/0.78125
(64000/x)*x=(100/0.78125)*x       - we multiply both sides of the equation by x
64000=128*x       - we divide both sides of the equation by (128) to get x
64000/128=x
500=x
x=500

now we have:
0.78125% of 64000=500
