What is 0.028 percent of 30000000 - 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 30000000 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 30000000 is 100%, so we can write it down as 30000000=100%.
4. We know, that x is 0.028% of the output value, so we can write it down as x=0.028%.
5. Now we have two simple equations:
1) 30000000=100%
2) x=0.028%
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:
30000000/x=100%/0.028%
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 0.028% of 30000000

30000000/x=100/0.028
(30000000/x)*x=(100/0.028)*x       - we multiply both sides of the equation by x
30000000=3571.4285714286*x       - we divide both sides of the equation by (3571.4285714286) to get x
30000000/3571.4285714286=x
8400=x
x=8400

now we have:
0.028% of 30000000=8400
