3/8•4/9

To multiply the fractions \( \frac{3}{8} \) and \( \frac{4}{9} \), you multiply the numerators together and the denominators together:

\[ \frac{3}{8} \times \frac{4}{9} = \frac{3 \times 4}{8 \times 9} = \frac{12}{72} \]

Now, simplify \( \frac{12}{72} \). Both the numerator and the denominator can be divided by 12:

\[ \frac{12 \div 12}{72 \div 12} = \frac{1}{6} \]

So, \( \frac{3}{8} \times \frac{4}{9} = \frac{1}{6} \).
