21
**To Add or Subtract Fractions With Unlike Denominators**

Find the multiples of each denominator. 1 5 = 5, 10, 15, 20, 25, 30 1 + 10 = 10, 20, 30, 40, 50

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. 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 2 1 + 8 = 8, 16, 24, 32, 40

26
**Find the Least Common Denominator or Least Common Multiple**

1 =10, 20, 30, 40, 10 1 + 8 = 8, 16, 24, 32, 40

27
**Find the Least Common Denominator or Least Common Multiple**

1 10 = 10, 20, 30, 40, 1 + = 4, 8, 12, 16, 20, 4

28
**Find the Least Common Denominator or Least Common Multiple**

1 2 = 2, 4, 6, 8, 10, 12 1 + = 4, 8, 12, 16, 20, 4

29
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

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. 1 3 will divide evenly into 9, so 9 is your LCD or LCM. 3 1 + 9

30
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 2 will divide evenly into 4, so 4 is your LCD or LCM. 2 1 + 4

31
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 2 will divide evenly into 10, so 10 is your LCD or LCM. 2 1 + 10

32
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 2 will divide evenly into 12, so 12 is your LCD or LCM. 2 1 + 12

33
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 4 will divide evenly into 8, so 8 is your LCD or LCM. 4 1 + 8

34
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 3 will divide evenly into 6, so 6 is your LCD or LCM. 3 1 + 6

35
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 3 will divide evenly into 12, so 12 is your LCD or LCM. 3 1 + 12

36
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 3 will divide evenly into 15, so 15 is your LCD or LCM. 3 1 + 15

37
**Shortcut for Finding the Least Common Denominator or Least Common Multiple**

Using the shortcut, what is the LCD or LCM? 1 3 will not divide evenly into 8, so find the least common multiple. 3 1 + 8
