Evaluate the expression. \[ 8 \div 2 \div 4 \times 1 \]

To evaluate the expression \( 8 \div 2 \div 4 \times 1 \), we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). 1. Start with the leftmost division: \[ 8 \div 2 = 4 \] 2. Now take the result and continue with the next division: \[ 4 \div 4 = 1 \] 3. Finally, multiply by 1: \[ 1 \times 1 = 1 \] Thus, the value of the expression \( 8 \div 2 \div 4 \times 1 \) is \( \boxed{1} \).
