### Step 1: Convert the percentage to a fraction
320% can be expressed as a fraction:
\[ 320\% = \frac{320}{100} \]

### Step 2: Write the expression for 320% of 40
Now we can express 320% of 40 mathematically:
\[ 320\% \text{ of } 40 = \frac{320}{100} \times 40 \]

### Step 3: Simplify the fraction
We can simplify \(\frac{320}{100}\) by canceling out the common zeros:
\[ \frac{320}{100} = \frac{32}{10} = \frac{16}{5} \]

### Step 4: Multiply the simplified fraction by 40
Now we multiply \(\frac{16}{5}\) by 40:
\[ \frac{16}{5} \times 40 = \frac{16 \times 40}{5} \]

### Step 5: Perform the multiplication
Calculating \(16 \times 40\):
\[ 16 \times 40 = 640 \]

### Step 6: Divide by 5
Now we divide 640 by 5:
\[ \frac{640}{5} = 128 \]

### Final Answer
