16 What is the Least Common Multiple of 3 & 8 8, 16, 24, 32, 40, 48 3, 6, 9, 12, 15, 18, 24 3 = 8 =

17 What is the Least Common Multiple of 4 & 8 8 = 8, 16, 24, 32, 40, 48 4 = 4, 8, 12, 16, 20, 24

18 What is the Least Common Multiple of 6 & 8 8 = 8, 16, 24, 32, 40, 48 6 = 6, 12, 18, 24, 30, 36

19 What is the Least Common Multiple of 4 & 10 10 = 10, 20, 30, 40, 50, 4 = 4, 8, 12, 16, 20, 24

20 What is the Least Common Multiple of 3 & 9 9 = 9, 18, 27, 36, 45, 54 3 = 3, 6, 9, 12, 15, 21,

21 To Add or Subtract Fractions With Unlike Denominators Find the multiples of each denominator. 1 = 5, 10, 15, 20, 25, 30 1 = 10, 20, 30, 40, 50 + 5 10

22 To Add or Subtract Fractions With Unlike Denominators Compare the lists of multiples. Circle the common multiples between the two lists. 1 5 = 5, 10, 15, 20, 25, 30 1 10 = 10, 20, 30, 40, 50 +

23 To Add or Subtract Fractions With Unlike Denominators Use the lowest common multiple as the denominator. 1 5 = 5, 10, 15,20,25,30 1 10 = 10, 20, 30, 40, 50 +

24 To Add or Subtract Fractions With Unlike Denominators This number is also called the least common denominator. This number is also called the least common denominator. 1 5 = 5, 10, 15,20,25,30 1 10 = 10, 20, 30, 40, 50 +

25 Find the Least Common Denominator or Least Common Multiple 1 = 2, 4, 6, 8, 10, 12 1 = 8, 16, 24, 32, 40 + 2 8

26 Find the Least Common Denominator or Least Common Multiple 1 =10, 20, 30, 40, 1 = 8, 16, 24, 32, 40 + 10 8

27 Find the Least Common Denominator or Least Common Multiple 1 = 10, 20, 30, 40, 1 = 4, 8, 12, 16, 20, + 4 10

28 Find the Least Common Denominator or Least Common Multiple 1 = 2, 4, 6, 8, 10, 12 1 = 4, 8, 12, 16, 20, + 4 2

29 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 3 1 9 + Check to see if the smaller denominator divides evenly into the larger denominator. If it does, use the larger denominator for your LCD or LCM. 3 will divide evenly into 9, so 9 is your LCD or LCM.

30 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 2 1 4 + Using the shortcut, what is the LCD or LCM? 2 will divide evenly into 4, so 4 is your LCD or LCM.

31 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 2 1 10 + Using the shortcut, what is the LCD or LCM? 2 will divide evenly into 10, so 10 is your LCD or LCM.

32 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 2 1 12 + Using the shortcut, what is the LCD or LCM? 2 will divide evenly into 12, so 12 is your LCD or LCM.

33 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 4 1 8 + Using the shortcut, what is the LCD or LCM? 4 will divide evenly into 8, so 8 is your LCD or LCM.

34 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 3 1 6 + Using the shortcut, what is the LCD or LCM? 3 will divide evenly into 6, so 6 is your LCD or LCM.

35 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 3 1 12 + Using the shortcut, what is the LCD or LCM? 3 will divide evenly into 12, so 12 is your LCD or LCM.

36 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 3 1 15 + Using the shortcut, what is the LCD or LCM? 3 will divide evenly into 15, so 15 is your LCD or LCM.

37 Shortcut for Finding the Least Common Denominator or Least Common Multiple 1 3 1 8 + Using the shortcut, what is the LCD or LCM? 3 will not divide evenly into 8, so find the least common multiple.
