**a. Simplify \( \frac{1}{6} \times \frac{1}{3} \):** Multiply the numerators and the denominators: \[ \frac{1 \times 1}{6 \times 3} = \frac{1}{18} \] **b. Simplify \( \frac{1}{7} \times \frac{2}{5} \):** Multiply the numerators and the denominators: \[ \frac{1 \times 2}{7 \times 5} = \frac{2}{35} \] **c. Simplify \( \frac{5}{9} \times \frac{2}{3} \):** Multiply the numerators and the denominators: \[ \frac{5 \times 2}{9 \times 3} = \frac{10}{27} \] **d. Simplify \( \frac{3}{8} \times \frac{1}{4} \):** Multiply the numerators and the denominators: \[ \frac{3 \times 1}{8 \times 4} = \frac{3}{32} \] **e. Simplify \( \frac{3}{10} \times \frac{2}{5} \):** Multiply the numerators and the denominators: \[ \frac{3 \times 2}{10 \times 5} = \frac{6}{50} \] Simplify \( \frac{6}{50} \) by dividing the numerator and the denominator by \(2\): \[ \frac{6 \div 2}{50 \div 2} = \frac{3}{25} \]
