Add & Subtract Mixed Numbers with No Regrouping 4-102

Add and subtract mixed numbers with common denominators. What's 4 1/3 + 2 1/3? Use partial sums to add. Since 4+2 = 6 and 1/3 + 1/3 = 2/3, the sum is the mixed number 6 2/3. What's 4 6/8 - 2 1/8? Use partial differences to subtract. Since 4-2 = 2 and 6/8 - 1/8 = 5/8, the difference is the mixed number 2 5/8.
