$\frac{26}{27}$

$=17×\frac {5}{6}+17×\frac {1}{6}$

$=17×(\frac {5}{6}+\frac {1}{6})$

$=17$

$=(\frac{32}{5}+\frac{32}{15})÷(\frac{4}{5}+\frac{4}{15})$

$=8$

$解:\frac{11}{12}x=33$

$x=33×\frac{12}{11}$

$x=36$

$解:7x-\frac{3}{2}=\frac{3}{5}$

$7x=\frac{21}{10}$

$x=\frac{3}{10}$

$(\frac{1}{10}+\frac{1}{5})×3=\frac{9}{10}(千克)$

$答：一共重\frac {9}{10}千克。$

$15×\frac{1}{5}×45=135(元)$

$135÷(\frac{1}{10}×30)=45(袋)$

$答：应付135元,可以买45袋。$

$苹果:120÷(\frac{7}{6}-\frac{9}{10})=450(千克)\ $

$梨:450÷\frac{6}{7}=525(千克)\ $

$答：这两种水果原来各有450千克,525千克。$

$600÷(\frac{2}{3}+\frac{3}{4}-1)=1440(米) $

$答：A、B两地相距1440米。$
