What is 0.02 percent of 4500000 - 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 4500000 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 4500000 is 100%, so we can write it down as 4500000=100%.
4. We know, that x is 0.02% of the output value, so we can write it down as x=0.02%.
5. Now we have two simple equations:
1) 4500000=100%
2) x=0.02%
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:
4500000/x=100%/0.02%
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 0.02% of 4500000

4500000/x=100/0.02
(4500000/x)*x=(100/0.02)*x       - we multiply both sides of the equation by x
4500000=5000*x       - we divide both sides of the equation by (5000) to get x
4500000/5000=x
900=x
x=900

now we have:
0.02% of 4500000=900
