Answer:

a) 28 = 1, 2, 4, 7, 14, 28

         = 1 + 2 + 4 + 7 + 14 + 28

         = 56

         = 56/28

         = 2, Yes

b) 30 = 1, 2, 3, 5, 6, 10, 15, 30

         = 1 + 2 + 3 + 5 + 6 + 10 + 15 + 30

         = 72

         = 72/30

         = 2.4, No

c) 14 = 1, 2, 7, 14

       = 1 + 2 + 7 + 14

       =  24

      = 24/14

      = 1.714, No

d) 16 = 1, 2, 4, 8, 16

        = 1 + 2 + 4 + 8 + 16

        = 31

        = 31/16

       = 1.9375, No
