What is 0.8 percent of 399950 - 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 399950 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 399950 is 100%, so we can write it down as 399950=100%.
4. We know, that x is 0.8% of the output value, so we can write it down as x=0.8%.
5. Now we have two simple equations:
1) 399950=100%
2) x=0.8%
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:
399950/x=100%/0.8%
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 0.8% of 399950

399950/x=100/0.8
(399950/x)*x=(100/0.8)*x       - we multiply both sides of the equation by x
399950=125*x       - we divide both sides of the equation by (125) to get x
399950/125=x
3199.6=x
x=3199.6

now we have:
0.8% of 399950=3199.6
