Answer:
3 1/3+2 3/4 = 73/12=6 1/12
Explanation:
1.Conversion a mixed number 3 1/3 to a improper fraction: 3 1/3 = 3 1/3 = 3 · 3 + 1/3 = 9 + 1/3= 10
2.Conversion a mixed number 2 3/4 to a improper fraction: 2 3/4 = 2 3/4 = 2 · 4 + 3/4 = 8 + 3/4= 11
3.Add: 10/3 + 11/4 = 10 · 4/3 · 4 + 11 · 3/4 · 3 = 40/12 + 33/12 = 40 + 33/12 = 73/12
