Answer 1

We were told that Michelle did 81 crunches in 3 minutes. This means that the number of crunches that Michelle did per minute is

81/3 = 27 crunches per minute

her friend Zach did 104 crunches in 4 minutes. This means that the number of crunches that Zach did per minute is

104/4 = 26 crunches per minute

Therefore, Michelle did more crunches per minute
