Simplify: $4 \div 8 \div 4 \times 4$
$\frac{1}{2}$
Expression Simplification: $4 \div 8 \div 4 \times 4$
To simplify the given mathematical expression, we follow the standard order of operations (PEMDAS/BODMAS). This means we perform division and multiplication from left to right.
Calculation Steps
- Original expression: $4 \div 8 \div 4 \times 4$
- First division (left to right): $4 \div 8 = \frac{4}{8} = \frac{1}{2}$. The expression becomes: $\frac{1}{2} \div 4 \times 4$.
- Next division: $\frac{1}{2} \div 4 = \frac{1}{2} \times \frac{1}{4} = \frac{1}{8}$. The expression becomes: $\frac{1}{8} \times 4$.
- Final multiplication: $\frac{1}{8} \times 4 = \frac{4}{8} = \frac{1}{2}$.
Simplified Result
The final simplified value of the expression $4 \div 8 \div 4 \times 4$ is $\frac{1}{2}$.
