Directions: Using the digits 1 to 9 at most one time each, fill in the boxes to make the smallest (or largest) quotient.

### Hint

What number does each box represent?

### Answer

The current smallest quotient is 1.23 / 9.87 = 0.124. No answers yet for the largest quotient. If you have one, post it in the comments.

Just a heads up on a typo: quotient, not sum

Good catch! Thanks. I’ll change it now.

1.23 / 9.87 = 0.124

Thanks DYMB! I added it to the problem.

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!!

9.87/1.23=8.024

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

The directions didn’t say that the quotient couldn’t repeat any of the digits — only the digits in the boxes can’t be repeated 🙂

largest is 9.87/1.23 = 8.0243902439

1.23 / 9.87 = 0.124

1.23 divided 9.87 = 0.124
