What is 20 percent of 162.84 - 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 162.84 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 162.84 is 100%, so we can write it down as 162.84=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 162.84=100%
2) x=20%
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:
162.84/x=100%/20%
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 20% of 162.84

162.84/x=100/20
(162.84/x)*x=(100/20)*x       - we multiply both sides of the equation by x
162.84=5*x       - we divide both sides of the equation by (5) to get x
162.84/5=x
32.568=x
x=32.568

now we have:
20% of 162.84=32.568
