Ответ:

  1. \[\left(\frac{1}{17}+1\frac{1}{4}\right):\frac{1}{34}=\left(\frac{1}{17}+\frac{5}{4}\right)\cdot34=\frac{89}{68}\cdot34=\frac{89}{2}=44\frac{1}{2}.\]
  2. \[\left(\frac{3}{4}-2\frac{9}{10}\right):\frac{1}{12}=\left(\frac{3}{4}-\frac{29}{10}\right)\cdot12=\left(\frac{15}{20}-\frac{58}{20}\right)\cdot12=-\frac{43}{20}\cdot12=-\frac{129}{5}=-25\frac{4}{5}.\]
  3. \[\left(\frac{7}{9}+1\frac{4}{5}\right):\frac{1}{18}=\left(\frac{7}{9}+\frac{9}{5}\right)\cdot18=\frac{116}{45}\cdot18=\frac{232}{5}=46\frac{2}{5}.\]
  4. \[\left(\frac{4}{11}-2\frac{1}{4}\right):\frac{1}{22}=\left(\frac{4}{11}-\frac{9}{4}\right)\cdot22=\frac{-83}{44}\cdot22=-\frac{83}{2}=-41\frac{1}{2}.\]
  5. \[\left(\frac{13}{24}+1\frac{1}{15}\right):\frac{1}{24}=\left(\frac{13}{24}+\frac{16}{15}\right)\cdot24=\frac{193}{120}\cdot24=\frac{193}{5}=38\frac{3}{5}.\]
  6. \[\left(\frac{15}{26}-2\frac{3}{4}\right):\frac{1}{26}=\left(\frac{15}{26}-\frac{11}{4}\right)\cdot26=\frac{-227}{52}\cdot26=-\frac{227}{2}=-113\frac{1}{2}.\]
