Multiplying and Dividing Fractions - StartLogic



W

e have worked hard to learn how to add and subtract fractions. In this activity, you will practice multiplying and dividing fractions, including some with both positive and negative signs. We will use prime factoring to help simplify the results.

1. [pic]= 2. [pic]=

3. [pic]= 4. [pic]=

5. [pic]= 6. [pic]=

7. [pic]= 8. [pic]=

9. [pic]= 10. [pic]=

11. [pic] = 12. [pic] =

13. [pic] = 14. [pic] =

15. [pic] = 16. [pic] =

17. [pic] = 18. [pic] =

19. [pic] = 20. [pic]=
