Answer 3

To solve the expression, let's first convert all the mixed numbers to improper fractions, then perform the operations step by step:

Step 1: Convert the mixed numbers to improper fractions: 3 3/8 = (3 * 8 + 3) / 8 = 27 / 8 3 1/5 = (3 * 5 + 1) / 5 = 16 / 5 4 1/6 = (4 * 6 + 1) / 6 = 25 / 6

Step 2: Perform the multiplication and division operations first: 27 / 8 × 16 / 5 = (27 × 16) / (8 × 5) = 432 / 40 = 54 / 5 25 / 6 × 16 / 5 = (25 × 16) / (6 × 5) = 400 / 30 = 40 / 3

Step 3: Perform the addition and subtraction operations: 54 / 5 + 40 / 3 = (54 × 3 + 40 × 5) / (5 × 3) = (162 + 200) / 15 = 362 / 15

Finally, we have: 3 3/8 × 3 1/5 + 3 1/5 × 15/12 - 4 1/6 × 3 1/5 = 362 / 15.

If needed, you can further simplify the fraction, but 362/15 is already a proper fraction.
