Answer
Correct Answer: $\frac{3}{2}$
Explanation
### Concept & Rule
This question strictly tests the application of the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction) applied independently to a numerator and a denominator.
Division and Multiplication have the same priority, so you must process them strictly from left to right as they appear in the expression.
### Step-by-Step Solution
* **Step 1:** Evaluate the numerator using BODMAS.
Expression: $3 + 4 \div 2 \times 3$
First, perform Division: $4 \div 2 = 2$.
The expression becomes: $3 + 2 \times 3$.
Next, perform Multiplication: $2 \times 3 = 6$.
The expression becomes: $3 + 6$.
Finally, Addition: $3 + 6 = 9$.
Numerator $= 9$.
* **Step 2:** Evaluate the denominator using BODMAS.
Expression: $4 + 3 \times 2 \div 3$
First, evaluate Multiplication and Division left-to-right.
Multiplication appears first: $3 \times 2 = 6$.
The expression becomes: $4 + 6 \div 3$.
Next, Division: $6 \div 3 = 2$.
The expression becomes: $4 + 2$.
Finally, Addition: $4 + 2 = 6$.
Denominator $= 6$.
* **Step 3:** Form the final fraction and simplify.
$$ x = \frac{9}{6} $$
Divide numerator and denominator by 3:
$$ x = \frac{3}{2} $$
### Exam Strategy & Shortcut
To avoid rewriting steps, group operations mentally. In the numerator, identify $4 \div 2 \times 3$ as a single operational block resulting in 6. In the denominator, identify $3 \times 2 \div 3$ as another block resulting in 2. You immediately get $\frac{3+6}{4+2} = \frac{9}{6} = \frac{3}{2}$. Speed comes from isolating multiplication/division chains from the addition terms.
### Common Pitfall
The most common trap is ignoring left-to-right execution for Division and Multiplication. In the denominator ($4 + 3 \times 2 \div 3$), a student might wrongly divide $2 \div 3$ first to get a fraction, complicating the sum. Always process $\times$ and $\div$ sequentially from left to right.
### Final Answer
**Therefore, the correct answer is \frac{3}{2}.**
