number is prime?).
Problems: Review the hw problems from this section.
§5.2: Know how to find GCF (a, b): Using the definition, using the prime
factorization

equal?), order of fractions ( if and only if
a·d < c·b), density property of fractions
(know how to find a fraction between any two given fractions, how many fractions
are there
between two given fractions?).
Problems: Review the hw problems from this section.
§6.2: Addition of fractions and its properties (closure property,
commutative property,
associative property, additive identity property). Subtraction of fractions .

estimation for addition and subtraction.
Problems: Review the hw problems from this section.
§6.3: Multiplication of fractions and its properties (closure property,
commutative property,
associative property, multiplicative identity property, distributive property
over addition
and subtraction of fractions, multiplicative inverse ( or reciprocal ) of a
fraction). Division of
fractions.
Problems: Set A, p. 269: 2, 4, 8g, 10, 15, 16, 20, 22.
