a) $\frac{7}{16} + 3\frac{1}{2} = \frac{7}{16} + \frac{7}{2} = \frac{7}{16} + \frac{56}{16} = \frac{63}{16} = 3\frac{15}{16}$ б) $7 - 4\frac{5}{9} = 6\frac{9}{9} - 4\frac{5}{9} = 2\frac{4}{9}$ в) $\frac{8}{9} - \frac{7}{12} = \frac{32}{36} - \frac{21}{36} = \frac{11}{36}$ г) $4\frac{3}{10} + 1\frac{5}{12} = 4\frac{18}{60} + 1\frac{25}{60} = 5\frac{43}{60}$ д) $9\frac{3}{8} - 1\frac{5}{24} + 7\frac{2}{4} = 9\frac{9}{24} - 1\frac{5}{24} + 7\frac{16}{24} = 15\frac{20}{24} = 15\frac{5}{6}$ е) $\frac{3}{8} : \frac{9}{16} = \frac{3}{8} \cdot \frac{16}{9} = \frac{1}{1} \cdot \frac{2}{3} = \frac{2}{3}$ ж) $48 : \frac{12}{13} = \frac{48}{1} \cdot \frac{13}{12} = \frac{4}{1} \cdot \frac{13}{1} = 52$ з) $\frac{11}{28} \cdot \frac{4}{33} = \frac{1}{7} \cdot \frac{1}{3} = \frac{1}{21}$ и) $2\frac{2}{3} \cdot 6 = \frac{8}{3} \cdot 6 = \frac{8}{1} \cdot 2 = 16$ к) $7\frac{11}{12} : 3\frac{1}{6} = \frac{95}{12} : \frac{19}{6} = \frac{95}{12} \cdot \frac{6}{19} = \frac{5}{2} \cdot \frac{1}{1} = 2\frac{1}{2}$
