What is 0.003 percent of 0.3 - 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 0.3 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 0.3 is 100%, so we can write it down as 0.3=100%.
4. We know, that x is 0.003% of the output value, so we can write it down as x=0.003%.
5. Now we have two simple equations:
1) 0.3=100%
2) x=0.003%
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:
0.3/x=100%/0.003%
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 0.003% of 0.3

0.3/x=100/0.003
(0.3/x)*x=(100/0.003)*x       - we multiply both sides of the equation by x
0.3=33333.333333333*x       - we divide both sides of the equation by (33333.333333333) to get x
0.3/33333.333333333=x
9.0E-6=x
x=9.0E-6

now we have:
0.003% of 0.3=9.0E-6
