To multiply the fractions \( \frac{3}{8} \) and \( \frac{4}{5} \), you multiply the numerators together and the denominators together:
\[ \frac{3 \times 4}{8 \times 5} = \frac{12}{40} \]
Next, simplify \( \frac{12}{40} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
\[ \frac{12 \div 4}{40 \div 4} = \frac{3}{10} \]
Looking at the options provided, none match \( \frac{3}{10} \). Could you double-check the answer choices or provide the correct options?
