What is 0.55 percent of 40.15 - 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 40.15 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 40.15 is 100%, so we can write it down as 40.15=100%.
4. We know, that x is 0.55% of the output value, so we can write it down as x=0.55%.
5. Now we have two simple equations:
1) 40.15=100%
2) x=0.55%
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:
40.15/x=100%/0.55%
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 0.55% of 40.15

40.15/x=100/0.55
(40.15/x)*x=(100/0.55)*x       - we multiply both sides of the equation by x
40.15=181.81818181818*x       - we divide both sides of the equation by (181.81818181818) to get x
40.15/181.81818181818=x
0.220825=x
x=0.220825

now we have:
0.55% of 40.15=0.220825
