What is 0.0032 percent of 1280 - 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 1280 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 1280 is 100%, so we can write it down as 1280=100%.
4. We know, that x is 0.0032% of the output value, so we can write it down as x=0.0032%.
5. Now we have two simple equations:
1) 1280=100%
2) x=0.0032%
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:
1280/x=100%/0.0032%
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 0.0032% of 1280

1280/x=100/0.0032
(1280/x)*x=(100/0.0032)*x       - we multiply both sides of the equation by x
1280=31250*x       - we divide both sides of the equation by (31250) to get x
1280/31250=x
0.04096=x
x=0.04096

now we have:
0.0032% of 1280=0.04096
