8. Mixed Numbers Mixed number: a whole number with a fraction! Example: 4 1/3 Fraction! Whole number!

9. Improper Fractions Improper fraction: a fraction that has a larger number in the numerator and a smaller number in the denominator. Example: 43/5 Larger number on top!

11. Solution!! 7/11 + 3/11 = 10/11

12. Adding Fractions cont… Rule Two: When the denominators are different find a common denominator and add using Rule One. Example: 2/3 + 1/2 = 4/6 + 3/6 = 7/6 2/3 x 2/2 = 4/6 and 1/2 x 3/3 = 3/6 Try your own! 1/4 + 3/2 = ?

13. Solution!! 1/4 + 3/2 = 2/8 + 12/8 = 14/8

14. Subtracting Fractions Rule One: If the denominator is the same in each fraction, then subtract the numerator and keep the denominator. Example: 3/5 – 1/5 = 2/5 Try your own! 7/13 – 4/13 = ?

15. Solution!! 7/13 – 4/13 = 3/13

16. Subtracting Fractions cont… Rule Two: If the denominator is different, find a common denominator and follow Rule One. Example: 2/3 – 1/6 = 4/6 – 1/6 = 3/6 2/3 x 2/2 = 4/6 Try your own! 2/3 – 1/5 = ?

17. Solution!! 2/3 – 1/5 = 10/15 – 3/15 = 7/15

18. Multiplying Factions Rule: Step One: Multiply the numerators by each other to get a new numerator. Step Two: Multiply the denominators by each other to a new denominator. Example: 3/5 x 4/7 = 12/35 3 x 4 = 12 and 5 x 7 = 35 Try your Own! 2/5 x 3/8 = ?

19. Solution!! 2/5 x 3/8 = 6/40

20. Dividing Fractions Rule: Step One: Flip the second fraction and change the division sign to a multiplication sign. Step Two: Follow the multiplication rule! Example: 6/7 ÷ 4/9 = 6/7 x 9/4 = 54/28 Try your own! 2/3 ÷ 3/5 = ?

21. Solution!! 2/3 ÷ 3/5 = 2/3 x 5/3 = 10/9

22. Good Luck on your test!!
