      My students got this today, too! We had a great discussion about thinking of this problem as a fraction instead of a division problem. Once a student got 0.5 as an answer, other students realized they could get 1/4 by making the dividend a quarter of the divisor. That led to 1/8. So fun!!

  3. 9.87/1.23=8.024

  4. My problem with either largest or smallest quotient is that your quotient repeats digits that were part of the divisor.

  5. largest is 9.87/1.23 = 8.0243902439
