Dividing mixed numbers starts by turning them into improper fractions. That conversion (and going back the other way) plus the flip idea are the feeder skills. Warm them up and mixed-number division is just one extra setup step.
These are words you'll need to already know to follow this lesson — not the new words the lesson teaches. Review each one, its meaning, and the example so the new lesson makes sense from the start.
Level 1 A counting number with no fraction or decimal part.
Example: 1, 2, and 3 are whole numbers.
Level 1 To add the same number many times to find a total.
Example: 1 × 2 equals 2.
Level 1 To put numbers together to find a total.
Example: 2 + 1 equals 3.
Level 1 The bottom number of a fraction; it tells how many equal parts the whole has.
Example: In 3/2, the denominator is 2.
These check the skills you'll need for this lesson — not the new lesson itself. Answer all 3, then press Show my path. No grade — it just suggests where to start.
1. Write 1 1/2 as an improper fraction (halves).
2. How many thirds (1/3) are in 1 whole?
3. What is the reciprocal (flip) of 3/2?
