What is the value of `(5.6 xx 0.36 + 0.42 xx 3.2)/(0.8 xx 2.1)` ?

Options

A. 2
B. 1
C. 3
D. `(3)/(2)`

Answer

To solve the expression \((5.6 \times 0.36 + 0.42 \times 3.2) / (0.8 \times 2.1)\), we can break it down step by step.

### Step 1: Calculate the numerator
We need to calculate \(5.6 \times 0.36\) and \(0.42 \times 3.2\) separately.

1. **Calculate \(5.6 \times 0.36\)**:
\[ 5.6 \times 0.36 = 2.016 \]

2. **Calculate \(0.42 \times 3.2\)**:
\[ 0.42 \times 3.2 = 1.344 \]

3. **Add the results**:
\[ 2.016 + 1.344 = 3.36 \]

### Step 2: Calculate the denominator
Now we calculate \(0.8 \times 2.1\):
\[ 0.8 \times 2.1 = 1.68 \]

### Step 3: Divide the numerator by the denominator
Now we divide the sum from the numerator by the result from the denominator:
\[ \frac{3.36}{1.68} = 2 \]

### Final Answer
The value of the expression \((5.6 \times 0.36 + 0.42 \times 3.2) / (0.8 \times 2.1)\) is \(2\).
