Practice: Dividing Fractions

Part A: Unit Fraction / Whole Number

Directions: Divide. Remember: When you divide a fraction by a whole number, the answer gets SMALLER. Use the rule: 1/a / b = 1/(a x b)

12 / 3 =

14 / 2 =

13 / 5 =

16 / 2 =

Directions: Divide. Remember: When you divide a whole number by a unit fraction, the answer gets BIGGER. Use the rule: a / 1/b = a x b

2 / 14 =

5 / 13 =

3 / 15 =

6 / 12 =

Directions: Use the model to solve. Write the division equation and answer.
