So the three numbers can be turned into fractions.
1/5, 1/4, and 4/20.
fractions can be turned into decimals by dividing the denominator into the numerator.
now we have 0.2 , 0.25 , and 0.2
greatest to least, the numbers are 0.25 , 0.2 , and 0.2
(both 0.2s are equal, so order of those doesn't matter)
