Answer 1

${ (\frac{5}{7} )}^{2} \times \frac{7}{15} = \frac{25}{49} \times \frac{7}{15} = \frac{5}{7} \times \frac{1}{3} = \frac{5}{21}$

${( \frac{3}{4} )}^{2} \times \frac{32}{45} = \frac{9}{16} \times \frac{32}{45} = 1 \times \frac{2}{5} = \frac{2}{5}$

${(2 \frac{1}{3} )}^{2} \times \frac{27}{98} = {( \frac{7}{3} )}^{2} \times \frac{27}{98} = \frac{49}{9} \times \frac{27}{98} = 1 \times \frac{3}{2} = 1 \frac{1}{2}$

${( \frac{8}{11} )}^{2} \times \frac{11}{32} = \frac{64}{ {11}^{2} } \times \frac{11}{32} = \frac{2}{11}$

${( \frac{1}{2} )}^{2} \times \frac{4}{5} = \frac{1}{4} \times \frac{4}{5} = \frac{1}{5}$

${(2 \frac{5}{7} )}^{2} \times \frac{14}{19} = {( \frac{19}{7}) }^{2} \times \frac{14}{19} = \frac{ {19}^{2} }{ {7}^{2} } \times \frac{14}{19} = \frac{19}{7} \times 2 = \frac{38}{7} = 5 \frac{3}{7}$

${( \frac{3}{10} )}^{2} \times \frac{5}{6} = \frac{9}{100} \times \frac{5}{6} = \frac{3}{20} \times \frac{1}{2} = \frac{3}{40}$

${( \frac{2}{3} )}^{3} \times \frac{15}{24} = \frac{8}{27} \times \frac{15}{24} = \frac{1}{9} \times \frac{5}{3} = \frac{5}{27}$
