Options

A. 8 7
B. 9. 8
C. 8 .0
D. 9.3

Answer

To solve the problem \( 744 \div 32 \times 0.4 \), we will follow these steps:

### Step 1: Divide 744 by 32
First, we need to perform the division of 744 by 32.

- **Calculation**:
- 32 goes into 74 two times (since \( 32 \times 2 = 64 \)).
- Subtract \( 64 \) from \( 74 \) to get \( 10 \).
- Bring down the next digit (4) to make it \( 104 \).
- 32 goes into 104 three times (since \( 32 \times 3 = 96 \)).
- Subtract \( 96 \) from \( 104 \) to get \( 8 \).
- Bring down a \( 0 \) to make it \( 80 \).
- 32 goes into 80 two times (since \( 32 \times 2 = 64 \)).
- Subtract \( 64 \) from \( 80 \) to get \( 16 \).
- Bring down a \( 0 \) to make it \( 160 \).
- 32 goes into 160 five times (since \( 32 \times 5 = 160 \)).
- Subtract \( 160 \) from \( 160 \) to get \( 0 \).

Thus, \( 744 \div 32 = 23.25 \).

### Step 2: Multiply the result by 0.4
Now we will multiply the result from the division by \( 0.4 \).

- **Calculation**:
- \( 23.25 \times 0.4 \)
- To perform this multiplication, we can break it down:
- \( 23.25 \times 0.4 = 23.25 \times \frac{4}{10} = \frac{23.25 \times 4}{10} \)
- Calculate \( 23.25 \times 4 \):
- \( 23.25 \times 4 = 93 \)
- Now divide by \( 10 \):
- \( \frac{93}{10} = 9.3 \)

Thus, \( 744 \div 32 \times 0.4 = 9.3 \).

### Final Answer
The final answer is \( 9.3 \).
