What is 0.0003 percent of 75000 - 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 75000 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 75000 is 100%, so we can write it down as 75000=100%.
4. We know, that x is 0.0003% of the output value, so we can write it down as x=0.0003%.
5. Now we have two simple equations:
1) 75000=100%
2) x=0.0003%
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:
75000/x=100%/0.0003%
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 0.0003% of 75000

75000/x=100/0.0003
(75000/x)*x=(100/0.0003)*x       - we multiply both sides of the equation by x
75000=333333.33333333*x       - we divide both sides of the equation by (333333.33333333) to get x
75000/333333.33333333=x
0.225=x
x=0.225

now we have:
0.0003% of 75000=0.225
