Options

A. 2.7
B. 0.27
C. 0.027
D. 0.0027

Answer

To find the product of \(0.03\) and \(0.9\), we can follow these steps:

### Step-by-Step Solution:

1. **Convert the decimals to fractions**:
- \(0.03\) can be written as \(\frac{3}{100}\) because there are two digits after the decimal point.
- \(0.9\) can be written as \(\frac{9}{10}\) because there is one digit after the decimal point.

2. **Multiply the fractions**:
- Now we multiply the two fractions:
\[ \frac{3}{100} \times \frac{9}{10} \]

3. **Multiply the numerators and denominators**:
- Multiply the numerators: \(3 \times 9 = 27\)
- Multiply the denominators: \(100 \times 10 = 1000\)
- So, we have:
\[ \frac{27}{1000} \]

4. **Convert the fraction back to a decimal**:
- To convert \(\frac{27}{1000}\) to a decimal, we can divide \(27\) by \(1000\). This gives us:
\[ 0.027 \]

### Final Answer:
The product of \(0.03\) and \(0.9\) is \(0.027\).
