\dfrac{1}{8} \times \dfrac{3}{4} \times \dfrac{2}{3}
= \dfrac{6}{96} or \dfrac{1}{16}

3.) 1 \dfrac{11}{15}
2 \dfrac{3}{5} \times \dfrac{2}{3}
= \dfrac{13}{5} \times \dfrac{2}{3}
= \dfrac{26}{15} or 1 \dfrac{11}{15}

4.) 13 \dfrac{17}{24}
= 7 \dfrac{5}{6} \times 1 \dfrac{3}{4}
= \dfrac{47}{6} \times \dfrac{7}{4}
= \dfrac{329}{24} \times 13 \dfrac{17}{24}

5.) 15 \dfrac{1}{12}
7 \times 2 \dfrac{3}{14}
= \dfrac{7}{1} \times \dfrac{31}{14}
= \dfrac{217}{14} or 15 \dfrac{7}{14} or 15 \dfrac{1}{2}

6.) \dfrac{8}{9}
\dfrac{2}{3} \div \dfrac{3}{4}
= \dfrac{3}{2} \times \dfrac{3}{4} = \dfrac{8}{9}

7.) \dfrac{1}{18}
= 15 \div \dfrac{5}{6}
= \dfrac{1}{15} \times \dfrac{5}{6} = \dfrac{5}{90} or \dfrac{1}{18}

8.) 10 \dfrac{2}{3}
\dfrac{3}{8} \div 4
= \dfrac{8}{3} \times \dfrac{4}{1} = \dfrac{32}{3} or 10 \dfrac{2}{3}

9.) \dfrac{12}{25}
1 \dfrac{2}{3} \div \dfrac{4}{5}
= \dfrac{5}{3} \div\dfrac{4}{5}
= \dfrac{3}{5} \times \dfrac{4}{5} = \dfrac{12}{25}

10.) \dfrac{1}{58}
7 \dfrac{1}{4} \div \dfrac{1}{8}
= \dfrac{29}{4} \div \dfrac{1}{8}
