156 ÷ 24 and 102 ÷ 15 both have a quotient of 6 and a remainder of 12.
a. are the division expressions equivalent to each other? use your knowledge of decimal division to justify your answer.
b. construct your own division problem with a two-digit divisor that has a quotient of 6 and a remainder of 12 but is not equivalent to the problems in 1(a).

Given that

a)

156/24 and 102/15 both have quotient of 6 and a remainder of 12.

  156/24:            

 24) 156 (6

       -144

          12

102/15 :

15) 102 (6

       -90

          12

So yes we can say that both have same quotient of 6 and a remainder of 12.

b)

132/20:

20) 132 (6

       -120

          12

240                     150                                 200

i think the correct option is the second option.
