Answer 1

To multiply the fractions \(-\frac{2}{5}\) and \(\frac{3}{10}\), follow these steps:

1. Multiply the numerators: \[ -2 \times 3 = -6 \]

2. Multiply the denominators: \[ 5 \times 10 = 50 \]

3. Combine the results to form the fraction: \[ \frac{-6}{50} \]

4. Simplify the fraction. The greatest common divisor (GCD) of 6 and 50 is 2, so we can divide the numerator and the denominator by 2: \[ \frac{-6 \div 2}{50 \div 2} = \frac{-3}{25} \]

Thus, the answer in simplest form is: \[ \boxed{-\frac{3}{25}} \]
