MIXED NUMBERS &
IMPROPER FRACTIONS
Presentation
• Before Thanksgiving Break, we learned how to add, subtract,
multiply and divide fractions by finding common denominators,
making equivalent fractions, simplifying, and finding the
reciprocal (division only).
• Today, you will be converting mixed numbers to improper
fractions and improper fractions to mixed numbers. We will use
key words convert, mixed number, and improper fraction.
Vocabulary
• convert – to change from
one form to another
• mixed number – a whole
number and a fraction
• improper fraction – a
fraction larger than one
whole; the numerator is
larger than the
denominator
Mixed Numbers
•A mixed number has a part that is a
whole and a part that is a fraction.
