What is 0.199 percent of 4.5 - 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 4.5 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 4.5 is 100%, so we can write it down as 4.5=100%.
4. We know, that x is 0.199% of the output value, so we can write it down as x=0.199%.
5. Now we have two simple equations:
1) 4.5=100%
2) x=0.199%
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:
4.5/x=100%/0.199%
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 0.199% of 4.5

4.5/x=100/0.199
(4.5/x)*x=(100/0.199)*x       - we multiply both sides of the equation by x
4.5=502.51256281407*x       - we divide both sides of the equation by (502.51256281407) to get x
4.5/502.51256281407=x
0.008955=x
x=0.008955

now we have:
0.199% of 4.5=0.008955
