CrusMann $\frac{1}{11}-\frac{1}{33} = \frac{3 - 1}{33} = \frac{2}{33}$
$\frac{7}{11}-\frac{5}{8} = \frac{56-55}{88} = \frac{1}{88}$
$\frac{13}{30}-\frac{2}{45}=\frac{39-4}{90} = \frac{35}{90}=\frac{7}{18}$
$\frac{13}{60} - \frac{7}{40} = \frac{26-21}{120} = \frac{5}{120} = \frac{1}{24}$

МатфакДВГУ74 1/11 -1/33 =3/33 -1/33=2/33
7/11 -5/8=56/88-55/88=1/88
13/30 - 2/45=39/90-4/90=35/90=7/18
13/60-7/40=26/120-21/120 = 5/120 =1/24
