What is 0.35 percent of 640000 - 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 640000 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 640000 is 100%, so we can write it down as 640000=100%.
4. We know, that x is 0.35% of the output value, so we can write it down as x=0.35%.
5. Now we have two simple equations:
1) 640000=100%
2) x=0.35%
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:
640000/x=100%/0.35%
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 0.35% of 640000

640000/x=100/0.35
(640000/x)*x=(100/0.35)*x       - we multiply both sides of the equation by x
640000=285.71428571429*x       - we divide both sides of the equation by (285.71428571429) to get x
640000/285.71428571429=x
2240=x
x=2240

now we have:
0.35% of 640000=2240
