Warm Up Add or subtract. π π + π π 2. π π + π π π π 1 π ππ
π π + π π π π + π π 3. π π - π ππ π π - π π π π 1 π ππ π ππ ππ ππ

Example 1: Add 12 π π + 3 π π Get a common denominator for the fractions. The LCD is 4. 12 π π = 12 π π + 3 π π x 2 = 3 π π Add the whole numbers and fractions. x 2 15 π π Make π π a mixed number. π π = 16 π π π π = 1 1 4
4
Example 2: Add 3 π π + 5 ππ ππ 3 π π = 3 ππ ππ ππ ππ = 1 π π + 5 ππ ππ = 5 ππ ππ 8 ππ ππ = π π = 9 π π
5
Example 3: Suppose a shark travels 25 π π miles in one hour and he travels 24 π π miles the next hour. How far did the shark travel during the two hours? 25 π π +ππ π π = 50 π ππ
6
Practice Add. 2 π π + 6 π π 12 π π π π 9 π ππ 2π π ππ

Closure Think of a problem where you add mixed numbers but the answer is not a mixed number. Answers vary. Fractions need to add to a whole number.
