• A. 11 1/19
• B. 11 19/20
• C. 10 19/20
• D. 13 1/20

Answer: (B)

To find the sum of 7 1/5 and 4 3/4, it’s helpful to first convert the mixed numbers into improper fractions. For 7 1/5: - Multiply the whole number (7) by the denominator (5): 7 × 5 = 35 - Add the numerator (1): 35 + 1 = 36 - Place this sum over the original denominator: 36/5 For 4 3/4: - Multiply the whole number (4) by the denominator (4): 4 × 4 = 16 - Add the numerator (3): 16 + 3 = 19 - Place this sum over the original denominator: 19/4 Now, add the two fractions: - Find a common denominator for 36/5 and 19/4. The least common multiple of 5 and 4 is 20. - Convert each fraction: - For 36/5, convert it to a denominator of 20: (36 × 4)/(5 × 4) = 144/20. - For 19/4, convert it to a denominator of 20: (19 ×
