What is 0.003 percent of 45000 - 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 45000 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 45000 is 100%, so we can write it down as 45000=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) 45000=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:
45000/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 45000

45000/x=100/0.003
(45000/x)*x=(100/0.003)*x       - we multiply both sides of the equation by x
45000=33333.333333333*x       - we divide both sides of the equation by (33333.333333333) to get x
45000/33333.333333333=x
1.35=x
x=1.35

now we have:
0.003% of 45000=1.35
