What is 0.042 percent of 72000000 - 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 72000000 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 72000000 is 100%, so we can write it down as 72000000=100%.
4. We know, that x is 0.042% of the output value, so we can write it down as x=0.042%.
5. Now we have two simple equations:
1) 72000000=100%
2) x=0.042%
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:
72000000/x=100%/0.042%
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 0.042% of 72000000

72000000/x=100/0.042
(72000000/x)*x=(100/0.042)*x       - we multiply both sides of the equation by x
72000000=2380.9523809524*x       - we divide both sides of the equation by (2380.9523809524) to get x
72000000/2380.9523809524=x
30240=x
x=30240

now we have:
0.042% of 72000000=30240
