Answer 3

To solve the expression (3 4/5 × (-4 5/19)) ÷ (-3), we'll perform the calculations step by step:

Step 1: Convert the mixed numbers into improper fractions: 3 4/5 = (5 × 3 + 4) / 5 = 19/5 -4 5/19 = (19 × -4 + 5) / 19 = -77/19

Step 2: Multiply the fractions: (19/5) × (-77/19) = (19 × -77) / (5 × 19) = -1463/95

Step 3: Divide the result by -3: (-1463/95) ÷ (-3) = (-1463/95) × (-1/3) = (1463/95) × (1/3) = 1463/285

Therefore, the result of the expression is 1463/285.
