Answer:
1/5% of 20, 10% of 20, 20% of 20
Explanation:
Percentages can be hard however instead of paying attention to the second number at first, look at the first number.
1/5, 10, 20.
Usually when your talking about percentages and putting them in order, every single second number will match. This makes it extremely easy as the smaller the first number, the less it would value.
Least because 1/5% of 20 has the smallest first number and when solved it equals 0.04.
Middle because 10% of 20 is the second smallest first number and when solved equals 2.
Greatest because 20% of 20 is the largest first number and when solved equals 2.
NOTE: THIS METHOD ONLY WORKS WHEN THE SECOND NUMBER IS THE SAME, OTHERWISE YOU MUST SOLVE IT IN ORDER TO FIGURE OUT WHICH IS WHICH.
