Using Number Properties

Problem: “List all the fractions less than 1 whole that can be made using only 3, 7, and 11.”(Answer: 3/7, 3/11, 7/11.)

Discuss which of those fractions is the smallest (3/11) and the largest (7/11).

Examples: Make the smallest fraction possible from two of these numbers:
3, 5, 1              7 10, 50,                      61 30, 7, 2 ...

Examples: Find the closest fraction to 1 possible from two of these numbers:
3, 5, 17                        10, 50, 61                   30, 7, 2 ...

Understanding Number Properties:

Make up a fraction that has a denominator greater than 100 and that is just a little bit more than 1/2.
