Options

A. `5.04`
B. `7.5`
C. `8.1`
D. `9.1`

Answer

To solve the question \((0.9\% \text{ of } 450) \div (0.2\% \text{ of } 250)\), we will follow these steps:

### Step 1: Calculate \(0.9\%\) of \(450\)
To find \(0.9\%\) of \(450\), we use the formula:
\[ \text{Percentage} = \left(\frac{\text{Percentage Value}}{100}\right) \times \text{Total Value} \]
So,
\[ 0.9\% \text{ of } 450 = \left(\frac{0.9}{100}\right) \times 450 \]
Calculating this gives:
\[ = 0.009 \times 450 = 4.05 \]

### Step 2: Calculate \(0.2\%\) of \(250\)
Next, we find \(0.2\%\) of \(250\) using the same formula:
\[ 0.2\% \text{ of } 250 = \left(\frac{0.2}{100}\right) \times 250 \]
Calculating this gives:
\[ = 0.002 \times 250 = 0.5 \]

### Step 3: Divide the results from Step 1 and Step 2
Now we will divide the result from Step 1 by the result from Step 2:
\[ \frac{0.9\% \text{ of } 450}{0.2\% \text{ of } 250} = \frac{4.05}{0.5} \]
Calculating this gives:
\[ = 8.1 \]

### Final Answer
Thus, \((0.9\% \text{ of } 450) \div (0.2\% \text{ of } 250) = 8.1\).
