The correct Answer is:
To solve the expression \( 4 \times 2 \div 3 \text{ of } 12 - 3 \div 2 (2 - 3) \times 2 + 3 \div 2 \text{ of } 3 \), we will follow the order of operations, often referred to as BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction). ### Step-by-Step Solution 1. **Evaluate the brackets**: \[ 2 - 3 = -1 \] So, the expression now becomes: \[ 4 \times 2 \div 3 \text{ of } 12 - 3 \div 2 \times (-1) \times 2 + 3 \div 2 \text{ of } 3 \] 2. **Evaluate the "of" (which means multiplication)**: - For \( 3 \text{ of } 12 \): \[ 3 \text{ of } 12 = 3 \times 12 = 36 \] - For \( 3 \text{ of } 3 \): \[ 3 \text{ of } 3 = 3 \times 3 = 9 \] Now the expression is: \[ 4 \times 2 \div 36 - 3 \div 2 \times (-1) \times 2 + 9 \] 3. **Evaluate the division and multiplication from left to right**: - For \( 4 \times 2 \div 36 \): \[ 4 \times 2 = 8 \quad \Rightarrow \quad 8 \div 36 = \frac{8}{36} = \frac{2}{9} \] - For \( 3 \div 2 \times (-1) \times 2 \): \[ 3 \div 2 = \frac{3}{2} \quad \Rightarrow \quad \frac{3}{2} \times (-1) = -\frac{3}{2} \quad \Rightarrow \quad -\frac{3}{2} \times 2 = -3 \] Now the expression is: \[ \frac{2}{9} - 3 + 9 \] 4. **Combine the terms**: - First, convert \( -3 \) to a fraction with a denominator of 9: \[ -3 = -\frac{27}{9} \] - Now, combine: \[ \frac{2}{9} - \frac{27}{9} + \frac{81}{9} = \frac{2 - 27 + 81}{9} = \frac{56}{9} \] 5. **Final result**: The value of the expression is: \[ \frac{56}{9} \]
