Answer:
5⅛ < 121/20 < 6.107 < 6.16
Explanation:
First I made all the fractions decimals.
121/20 = 6.05
5⅛ can be turned into the improper fraction 41/8 which is 5.125 as a decimal.
From there you just order the number from least to greatest by looking to see what number is the biggest when looking from right to left.
For example 5 is smaller than 6 so 5.125 (5⅛) is the smallest. Then look at the tenth place and then the hundredths place to determine the next biggest number.
