What is 17.99 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 17.99% of the output value, so we can write it down as x=17.99%.
5. Now we have two simple equations:
1) 20=100%
2) x=17.99%
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%/17.99%
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 17.99% of 20

20/x=100/17.99
(20/x)*x=(100/17.99)*x       - we multiply both sides of the equation by x
20=5.5586436909394*x       - we divide both sides of the equation by (5.5586436909394) to get x
20/5.5586436909394=x
3.598=x
x=3.598

now we have:
17.99% of 20=3.598
