To simplify (28 ÷ 4 \cdot 3), you follow the order of operations, which is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). In this expression, division and multiplication are on the same level, so you perform them from left to right. First, you divide 28 by 4 to get 7, then you multiply 7 by 3 to get 21. Therefore, (28 ÷ 4 \cdot 3) simplifies to (21).
