Пошаговое объяснение:

1) $14\frac{1}{4} +7\frac{5}{6} =\frac{4*14+1}{4} +\frac{6*7+5}{6} =\frac{57}{4} +\frac{47}{6} =\frac{57*3+47*2}{12}= \frac{171+94}{12} =\frac{265}{12} =22\frac{1}{12}$

2) $4\frac{11}{18} +8\frac{7}{12} =\frac{18*4+11}{18} +\frac{12*8+7}{12} =\frac{83}{18} +\frac{103}{12} =\frac{83*2+103*3}{36} =\frac{166+309}{36} =\frac{475}{36} =13\frac{7}{36}$

3) $7\frac{5}{24} +2\frac{3}{16} =\frac{24*7+5}{24} +\frac{16*2+3}{16} =\frac{173}{24} +\frac{35}{16}=\frac{173*2+35*3}{48}=\frac{346+105}{48}=\frac{451}{48} = 9\frac{19}{48}$

4) $7\frac{5}{16} +4\frac{1}{6} +3\frac{3}{8} =\frac{16*7+5}{16} +\frac{6*4+1}{6} +\frac{3*8+3}{8} =\frac{117}{16}+\frac{25}{6}+\frac{27}{8} =\frac{117*3+25*8+27*6}{48} = \frac{351+200+162}{48} =\frac{713}{48} =14\frac{41}{48}$
