What is 0.049 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 0.049% of the output value, so we can write it down as x=0.049%.
5. Now we have two simple equations:
1) 4000=100%
2) x=0.049%
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%/0.049%
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 0.049% of 4000

4000/x=100/0.049
(4000/x)*x=(100/0.049)*x       - we multiply both sides of the equation by x
4000=2040.8163265306*x       - we divide both sides of the equation by (2040.8163265306) to get x
4000/2040.8163265306=x
1.96=x
x=1.96

now we have:
0.049% of 4000=1.96
