ДАЮ 30 БАЛЛОВ!!!!! 378!! ПОМОГИТЕ ПОЖАЛУЙСТА РЕШИТЬ :)

Решите задачу:

$\frac{1}{4} - (1 - \frac{11}{12} ) = \frac{1}{4} - \frac{1}{1} + \frac{11}{12} = \frac{3 - 12 + 11}{12} = \frac{2}{12} = \frac{1}{6} \\ 2 - ( \frac{13}{33} - \frac{5}{22} ) = \frac{2}{1} - \frac{13}{33} + \frac{5}{22} = \frac{132 - 26 + 15}{66} = \frac{121}{66} = 1 \frac{55}{66} \\ 6 \frac{3}{16} - (2 \frac{3}{8} + 3 \frac{5}{12} ) = \frac{99}{16} - \frac{19}{8} - \frac{41}{12} = \frac{297 - 114 - 164}{48} = \frac{19}{48} \\$
