Directions: Using the digits 1 through 9 at most one time each, fill in the boxes to create the smallest (or largest) whole number quotient.
Hint
What does the number on the left represent? What does the number on the right represent? What digits should we use? Which digits should we not use?
Answer
Smallest: 126 ÷ 9 = 14
Largest: 987 ÷ 1 = 987
Largest: 987 ÷ 1 = 987

I really like this problem! I actually got a different answer by dividing 123/9 which is 13 2/3. I’m going to share this with some teachers tomorrow and I may add something along the lines as “without a remainder”.
(0x1)+(2×3)=6
0+6=6
Never mind! I just read the problem again alittle more carefully and saw the words “whole number quotient”! Great problem, thanks!

6 9 3 ,1 2 9 (3+6=9) something when wrong and I don’t know what happen but
-6 3 I tried my best.

456\9=211
100/5 = 20
by using 20 nickels
102/6 = 17
110/10=11
2/1=2
246/2=123
2/1=2
126 divided by 5=25
126 divided by 9 equals 14
I did 286 divided by 4 = 71.2 or 71 with a remainder of 2
987 divide 1= 987 it is the only thing I could come up with
