What is 0.075 percent of 0.003 - 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 0.003 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 0.003 is 100%, so we can write it down as 0.003=100%.
4. We know, that x is 0.075% of the output value, so we can write it down as x=0.075%.
5. Now we have two simple equations:
1) 0.003=100%
2) x=0.075%
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:
0.003/x=100%/0.075%
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 0.075% of 0.003

0.003/x=100/0.075
(0.003/x)*x=(100/0.075)*x       - we multiply both sides of the equation by x
0.003=1333.3333333333*x       - we divide both sides of the equation by (1333.3333333333) to get x
0.003/1333.3333333333=x
2.25E-6=x
x=2.25E-6

now we have:
0.075% of 0.003=2.25E-6
