Answer 1

$\displaystyle a). \frac{3}{8} : \frac{9}{2} = \frac{3}{8} \cdot \frac{2}{9} = \frac{6}{72} = \frac{1}{12} \\ \\ b). \frac{7}{15} : \frac{14}{5} = \frac{7}{15} \cdot \frac{5}{14} = \frac{35}{210} = \frac{1}{6} \\ \\ c).4 \frac{1}{3} : \frac{26}{7} = \frac{13}{3} : \frac{26}{7} = \frac{13}{3} \cdot \frac{7}{26} = \frac{91}{78} \\ \\ d). \frac{28}{3} :5 \frac{1}{4} = \frac{28}{3} : \frac{21}{4} = \frac{28}{3} \cdot \frac{4}{21} = \frac{112}{63} = \frac{16}{9}$
