Question

3 which simplification is correct?
a $8 \div 2 \times 4$
\quad\quad $4 \times 4$
\quad\quad $16$
c $8 \div 2 \times 4$
\quad\quad $8 \times 8$
\quad\quad $64$
b $8 \div 2 \times 4$
\quad\quad $8 \div 8$
\quad\quad $1$
d $8 \div 2 \times 4$
\quad\quad $16 \div 4$
\quad\quad $4$

Explanation:

Step1: Apply order of operations

For $8÷2×4$, perform division first: $8÷2 = 4$

Step2: Multiply the result

$4×4 = 16$

Step3: Check other options

Option B incorrectly does multiplication first ($2×4=8$ then $8÷8=1$). Option C incorrectly replaces $÷2×4$ with $×8$. Option D has wrong intermediate steps. Only A follows order of operations.

Answer:

A. 8÷2×4 = 4×4 = 16
