What is 21.75 percent of 165 - 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 165 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 165 is 100%, so we can write it down as 165=100%.
4. We know, that x is 21.75% of the output value, so we can write it down as x=21.75%.
5. Now we have two simple equations:
1) 165=100%
2) x=21.75%
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:
165/x=100%/21.75%
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 21.75% of 165

165/x=100/21.75
(165/x)*x=(100/21.75)*x       - we multiply both sides of the equation by x
165=4.5977011494253*x       - we divide both sides of the equation by (4.5977011494253) to get x
165/4.5977011494253=x
35.8875=x
x=35.8875

now we have:
21.75% of 165=35.8875
