What is 0.3125 percent of 0.281 - 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 0.281 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 0.281 is 100%, so we can write it down as 0.281=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) 0.281=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:
0.281/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 0.281

0.281/x=100/0.3125
(0.281/x)*x=(100/0.3125)*x       - we multiply both sides of the equation by x
0.281=320*x       - we divide both sides of the equation by (320) to get x
0.281/320=x
0.000878125=x
x=0.000878125

now we have:
0.3125% of 0.281=0.000878125
