Math 2-3: Multiplying Rational Numbers Objective: To multiply fractions

Vocabulary dimensional analysis – the process of including units of measurement when you compute. greatest common factor (GCF) – the greatest of the factors common to two or more numbers.

Multiplying Fractions To multiply factions, multiply the numerators and multiply the denominators. Negative fractions – same rules apply as with multiplying integers. Always divide out common factors before multiplying (simplify).

Examples *multiply and write in simplest form*

Multiplying Mixed Numbers To multiply mixed numbers, first rewrite them as improper fractions. Always divide out common factors before multiplying (simplify).
