What is 0.135 percent of 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 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 3 is 100%, so we can write it down as 3=100%.
4. We know, that x is 0.135% of the output value, so we can write it down as x=0.135%.
5. Now we have two simple equations:
1) 3=100%
2) x=0.135%
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:
3/x=100%/0.135%
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 0.135% of 3

3/x=100/0.135
(3/x)*x=(100/0.135)*x       - we multiply both sides of the equation by x
3=740.74074074074*x       - we divide both sides of the equation by (740.74074074074) to get x
3/740.74074074074=x
0.00405=x
x=0.00405

now we have:
0.135% of 3=0.00405
