$\frac{9}{8}$

$\frac{13}{6}$

$\frac{2}{5}$

解$：0.4x-6=26$

$0.4x=32$

$ x = 80$

解$：x+\frac {1}{9}=1$

$x=1-\frac {1}{9}$

$x=\frac {8}{9}$

解$：2.5x=10$

$x = 4$

$=\frac {10}{12}-\frac {9}{12}+\frac {4}{12}$

$=\frac {1}{12}+\frac {4}{12}$

$= \frac {5}{12}$

$=7-(\frac {7}{19}+\frac {12}{19})$

$=7-1$

$= 6$

$=\frac {4}{3}-(\frac {19}{18}-\frac {1}{9})$

$=\frac {4}{3}-\frac {17}{18}$

$=\frac {24}{18}-\frac {17}{18}$

$= \frac {7}{18}$

$=(\frac {7}{11}+\frac {15}{11})-(\frac {2}{15}+\frac {8}{15})$

$=2-\frac {2}{3}$

$= \frac {4}{3}$

$=\frac {12}{5}-\frac {1}{5}-\frac {4}{5}$

$=\frac {12}{5}-(\frac {1}{5}+\frac {4}{5})$

$=\frac {12}{5}-1$

$=\frac {7}{5}$

$=(14.5-4.5)+(\frac {5}{8}+\frac {7}{8})$

$=10+1\frac {1}{2}$

$=11\frac {1}{2}$
