2. Table D: Table E:
3. The decimal representations for the factions are:
= 0.36, = 0.4, = 0.6, = 0.8
4. Answers will vary. Students should notice that all
denominators have at least factors of either 2 or 5
or both 2 and 5 only in their prime factorization.
Notice that 2 and 5 are factors of 10 (base 10).
5. Table F:
= 0.3, = 0.6
Table G:
= 0.16, = 0.3, = 0.5, = 0.6, = 0.83
6. Answers will vary. The decimals in Tables F and
G repeat except for = = 0.5. Guide students
to discover that the prime factorization of 3 and 6
does not contain a factor of 2 and/or 5. The
fractions in Tables F and G cannot be written as a
fraction with a denominator that is a power of 10
except which simplifies to . This will help
