What is 4.55 percent of 40 - 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 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 is 100%, so we can write it down as 40=100%.
4. We know, that x is 4.55% of the output value, so we can write it down as x=4.55%.
5. Now we have two simple equations:
1) 40=100%
2) x=4.55%
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/x=100%/4.55%
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 4.55% of 40

40/x=100/4.55
(40/x)*x=(100/4.55)*x       - we multiply both sides of the equation by x
40=21.978021978022*x       - we divide both sides of the equation by (21.978021978022) to get x
40/21.978021978022=x
1.82=x
x=1.82

now we have:
4.55% of 40=1.82
