What is 0.0024 percent of 30.8 - 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 30.8 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 30.8 is 100%, so we can write it down as 30.8=100%.
4. We know, that x is 0.0024% of the output value, so we can write it down as x=0.0024%.
5. Now we have two simple equations:
1) 30.8=100%
2) x=0.0024%
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:
30.8/x=100%/0.0024%
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 0.0024% of 30.8

30.8/x=100/0.0024
(30.8/x)*x=(100/0.0024)*x       - we multiply both sides of the equation by x
30.8=41666.666666667*x       - we divide both sides of the equation by (41666.666666667) to get x
30.8/41666.666666667=x
0.0007392=x
x=0.0007392

now we have:
0.0024% of 30.8=0.0007392
