Answer:

2.1.1 2 or 3 digits

Explanation:

2.1.1 In another problem, Paul, Jean, Charlie and Nox are given a three-digit dividend and a one-digit divisor. Can you help them predict how many digits will be in the quotient? Give examples to support your answer.

Start with the smallest 3-digit number and the largest 1-digit divisor that will divide evenly.

108/9 = 12

Now, use the largest 3-digit number and the smallest 1-digit number that divide evenly.

999/1 = 999

The quotient has 2 or 3 digits.
