Let's solve each of the problems step by step. ### Problem 1 \[ \frac{7}{8} \times \frac{2}{3} = \frac{7 \times 2}{8 \times 3} = \frac{14}{24} \] Now, we can simplify \(\frac{14}{24}\): \[ \frac{14 \div 2}{24 \div 2} = \frac{7}{12} \] So, the final answer is: \[ \frac{7}{12} \] ### Problem 2 \[ \frac{3}{4} \times \frac{5}{9} = \frac{3 \times 5}{4 \times 9} = \frac{15}{36} \] Now, we can simplify \(\frac{15}{36}\): \[ \frac{15 \div 3}{36 \div 3} = \frac{5}{12} \] So, the final answer is: \[ \frac{5}{12} \] ### Problem 3 \[ \frac{4}{5} \times \frac{1}{8} = \frac{4 \times 1}{5 \times 8} = \frac{4}{40} \] Now, we can simplify \(\frac{4}{40}\): \[ \frac{4 \div 4}{40 \div 4} = \frac{1}{10} \] So, the final answer is: \[ \frac{1}{10} \] ### Problem 5 \[ \frac{3}{5} \times \frac{3}{7} = \frac{3 \times 3}{5 \times 7} = \frac{9}{35} \] So, the final answer is: \[ \frac{9}{35} \] ### Problem 7 \[ \frac{11}{12} \times \frac{2}{5} = \frac{11 \times 2}{12 \times 5} = \frac{22}{60} \] Now, we can simplify \(\frac{22}{60}\): \[ \frac{22 \div 2}{60 \div 2} = \frac{11}{30} \] So, the final answer is: \[ \frac{11}{30} \] ### Problem 8 \[ \frac{2}{3} \times \frac{4}{5} = \frac{2 \times 4}{3 \times 5} = \frac{8}{15} \] So, the final answer is: \[ \frac{8}{15} \] ### Problem 9 \[ \frac{1}{6} \times \frac{2}{3} = \frac{1 \times 2}{6 \times 3} = \frac{2}{18} \] Now, we can simplify \(\frac{2}{18}\): \[ \frac{2 \div 2}{18 \div 2} = \frac{1}{9} \] So, the final answer is: \[ \frac{1}{9} \] ### Problem 10 \[ \frac{3}{4} \text{ of } \frac{1}{2} = \frac{3}{4} \times \frac{1}{2} = \frac{3 \times 1}{4 \times 2} = \frac{3}{8} \] So, the final answer is: \[ \frac{3}{8} \] ### Summary of Answers 1. \(\frac{7}{12}\) 2. \(\frac{5}{12}\) 3. \(\frac{1}{10}\) 4. \(\frac{9}{35}\) 5. \(\frac{11}{30}\) 6. \(\frac{8}{15}\) 7. \(\frac{1}{9}\) 8. \(\frac{3}{8}\)
