    $1, \frac{-7}{12}+\frac{11}{8}-\frac{5}{9}$
     $=\frac{-42}{72}+\frac{99}{72}-\frac{40}{72}$
     $=\frac{-42+99-40}{72}$
     $=\frac{17}{72}$
    $2, \frac{1}{7}-\frac{8}{7}:8-3:\frac{3}{4}.2^{2}$
     $=\frac{1}{7}-\frac{1}{7}-\frac{1}{4}.4$
     $=-1$
    $3, 1,4.\frac{15}{49}-(\frac{4}{5}+\frac{2}{3}):2\frac{1}{5}$
    $=\frac{3}{7}-\frac{22}{15}:\frac{11}{5}$
    $=\frac{3}{7}-\frac{2}{3}$
    $=\frac{-5}{21}$
