What is a n b? a={2,3,4,5,6} b= {3,6,9,12,15} a.) {3,6} b.) {9,12,15} c.) {2,4,5} d.) {2,4,5,9,12,15}

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
