What is 0.045 percent of 5.05 - 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 5.05 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 5.05 is 100%, so we can write it down as 5.05=100%.
4. We know, that x is 0.045% of the output value, so we can write it down as x=0.045%.
5. Now we have two simple equations:
1) 5.05=100%
2) x=0.045%
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:
5.05/x=100%/0.045%
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 0.045% of 5.05

5.05/x=100/0.045
(5.05/x)*x=(100/0.045)*x       - we multiply both sides of the equation by x
5.05=2222.2222222222*x       - we divide both sides of the equation by (2222.2222222222) to get x
5.05/2222.2222222222=x
0.0022725=x
x=0.0022725

now we have:
0.045% of 5.05=0.0022725
