A=[ 1/4, 3/8, 1/10, 7/25, 5/16 ] Look at the fractions in set B. B=[ 1/3, 5/6, 3/7, 7/12, 5/18 } Now each of the numbers in set C is a type of number that belongs in exactly one of the sets A or B. Determine the basic distinction between set A and set B and then identify each number in set C with one of the two sets if C=[ 1/5, 7/24, 3/32, 2/9, 7/36 ] --------------------------------------------------------------------
