What is 0.28 percent of 128000 - 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 128000 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 128000 is 100%, so we can write it down as 128000=100%.
4. We know, that x is 0.28% of the output value, so we can write it down as x=0.28%.
5. Now we have two simple equations:
1) 128000=100%
2) x=0.28%
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:
128000/x=100%/0.28%
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 0.28% of 128000

128000/x=100/0.28
(128000/x)*x=(100/0.28)*x       - we multiply both sides of the equation by x
128000=357.14285714286*x       - we divide both sides of the equation by (357.14285714286) to get x
128000/357.14285714286=x
358.4=x
x=358.4

now we have:
0.28% of 128000=358.4
