What is 0.007 percent of 42000000 - 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 42000000 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 42000000 is 100%, so we can write it down as 42000000=100%.
4. We know, that x is 0.007% of the output value, so we can write it down as x=0.007%.
5. Now we have two simple equations:
1) 42000000=100%
2) x=0.007%
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:
42000000/x=100%/0.007%
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 0.007% of 42000000

42000000/x=100/0.007
(42000000/x)*x=(100/0.007)*x       - we multiply both sides of the equation by x
42000000=14285.714285714*x       - we divide both sides of the equation by (14285.714285714) to get x
42000000/14285.714285714=x
2940=x
x=2940

now we have:
0.007% of 42000000=2940
