What is 0.19 percent of 4000 - 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 4000 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 4000 is 100%, so we can write it down as 4000=100%.
4. We know, that x is 0.19% of the output value, so we can write it down as x=0.19%.
5. Now we have two simple equations:
1) 4000=100%
2) x=0.19%
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:
4000/x=100%/0.19%
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 0.19% of 4000

4000/x=100/0.19
(4000/x)*x=(100/0.19)*x       - we multiply both sides of the equation by x
4000=526.31578947368*x       - we divide both sides of the equation by (526.31578947368) to get x
4000/526.31578947368=x
7.6=x
x=7.6

now we have:
0.19% of 4000=7.6
