What is 0.3125 percent of 200800 - 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 200800 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 200800 is 100%, so we can write it down as 200800=100%.
4. We know, that x is 0.3125% of the output value, so we can write it down as x=0.3125%.
5. Now we have two simple equations:
1) 200800=100%
2) x=0.3125%
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:
200800/x=100%/0.3125%
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 0.3125% of 200800

200800/x=100/0.3125
(200800/x)*x=(100/0.3125)*x       - we multiply both sides of the equation by x
200800=320*x       - we divide both sides of the equation by (320) to get x
200800/320=x
627.5=x
x=627.5

now we have:
0.3125% of 200800=627.5
