What is 0.015 percent of 1.9 - 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 1.9 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 1.9 is 100%, so we can write it down as 1.9=100%.
4. We know, that x is 0.015% of the output value, so we can write it down as x=0.015%.
5. Now we have two simple equations:
1) 1.9=100%
2) x=0.015%
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:
1.9/x=100%/0.015%
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 0.015% of 1.9

1.9/x=100/0.015
(1.9/x)*x=(100/0.015)*x       - we multiply both sides of the equation by x
1.9=6666.6666666667*x       - we divide both sides of the equation by (6666.6666666667) to get x
1.9/6666.6666666667=x
0.000285=x
x=0.000285

now we have:
0.015% of 1.9=0.000285
