`(12 xx 5 div 4) xx 8 = ?`

Options

A. 100
B. 140
C. 120
D. 80

Answer

To solve the expression `(12 xx 5 div 4) xx 8 = ?`, we will follow the order of operations, commonly known as BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Identify the operations**: The expression contains multiplication (xx) and division (div). According to BODMAS, we perform division before multiplication.

2. **Perform the division**:
\[ 12 \times 5 \div 4 \]
First, we calculate \(5 \div 4\):
\[ 5 \div 4 = 1.25 \]
Now, we multiply this result by 12:
\[ 12 \times 1.25 = 15 \]

3. **Multiply the result by 8**:
Now we take the result from the previous step and multiply it by 8:
\[ 15 \times 8 = 120 \]

4. **Final result**:
Therefore, the value of the expression is:
\[ ? = 120 \]

### Conclusion:
The answer is \(120\).
