Topic 9 Multiplying and Dividing Fractions

dividing fractions

• 1. If a whole number, add a 1 as denominator of whole number. 2. Multiply the numerators. 3. Multiply the denominators.

• Invert (reciprocal) the second fraction and multiply; Keep Change Flip

• Find common denominators and add numerators, denominators stay the same

• Find common denominators and subtract numerators, denominators stay the same

improper fraction

• a fraction whose numerator is larger than the denominator

• a fraction with a numerator of 1

• a number made up of a whole number and a fraction

• a number without fractions

mixed number

• a fraction whose numerator is larger than the denominator

• a fraction with a numerator of 1

• a number made up of a whole number and a fraction

• a number without fractions

multiple

• the answer to a multiplication problem

• the answer to a division problem

• the product of a number and any whole number

• a fraction with a numerator of 1
