Answer 3

To solve this expression, we'll follow the order of operations (also known as PEMDAS/BODMAS). Here's the step-by-step solution:

Step 1: Simplify the expression within the parentheses.

7 - 2/3 = (21/3) - 2/3 = 19/3

1 3/4 - 1/6 = (7/4) - 1/6 = 42/24 - 4/24 = 38/24 = 19/12

Step 2: Rewrite the division as multiplication by the reciprocal.

(19/3) ÷ (19/12) = (19/3) × (12/19)

Step 3: Simplify the multiplication.

(19/3) × (12/19) = (19 × 12) / (3 × 19) = 228/57 = 4

Step 4: Simplify the addition within the parentheses.

1 1/5 + 2 2/3 + 1/6 = (6/5) + (8/3) + (1/6) = (36/30) + (40/30) + (5/30) = 81/30

Step 5: Multiply the results from Step 3 and Step 4.

4 × (81/30) = (4 × 81) / 30 = 324/30 = 54/5

Therefore, the final result is 54/5.
