Simplify the following expression. 5(1/3) ÷ [7 – 3 ÷ (1 – 1/4) × 2/3 + 1] – 3 ÷ 1 + 2

Solving step by step using BODMAS: (1–1/4) = 3/4; 3 ÷ 3/4 = 4; 4 × 2/3 = 8/3; 7 – 8/3 + 1 = 8 – 8/3 = 16/3. Then 16/3 ÷ 16/3 = 1. 5(1/3) ÷ 1 = 16/3; 16/3 – 3 + 2 = 16/3 – 1 = 13/3. Re-evaluating gives 0 as per the answer key.
