Multiple Choice

Cayman says that 94 ÷ 3 is 30 with a remainder of 4. He reasons this is correct because (3 × 30) + 4 = 94. What mistake has Cayman made? Explain how he can correct his work.

• His mistake is that the remainder is greater than his divisor. He can divide even more.

• His mistake is that he did not have to add 4 to his multiplying. He should have added 3.

• His mistake that he made is that he multiplied 3 x 30 wrong. He then got 94 and therefore should have got 31.
