Explanation

Approximate all decimals as 2: the expression becomes 2 ÷ 2 ÷ 2 × 2 ÷ 2 ÷ 2. Working left to right: (2÷2)=1, then 1÷2=0.5, then 0.5×2=1, then 1÷2=0.5, then 0.5÷2=0.25. The key is maintaining order of operations and recognizing that consecutive divisions and multiplications cancel out strategically.
