What is 22.49 percent of 20 - 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 20 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 20 is 100%, so we can write it down as 20=100%.
4. We know, that x is 22.49% of the output value, so we can write it down as x=22.49%.
5. Now we have two simple equations:
1) 20=100%
2) x=22.49%
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:
20/x=100%/22.49%
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 22.49% of 20

20/x=100/22.49
(20/x)*x=(100/22.49)*x       - we multiply both sides of the equation by x
20=4.4464206313917*x       - we divide both sides of the equation by (4.4464206313917) to get x
20/4.4464206313917=x
4.498=x
x=4.498

now we have:
22.49% of 20=4.498
