Answer 1

Ответ:

а)

$1 - \frac{5}{6} = \frac{6}{6} - \frac{5}{6} = \frac{1}{6}$

б)

$8 \frac{3}{4} - 7 \frac{5}{6} = \frac{35}{4} - \frac{47}{6} = \frac{105}{12} - \frac{94}{12} = \frac{11}{12}$

в)

$5 - 2\frac{5}{9} = 4 \frac{9}{9} - 2 \frac{5}{9} = 2 \frac{4}{9}$

г)

$2 \frac{5}{8} - 1 \frac{3}{10} = \frac{21}{8} - \frac{13}{10} = \frac{210}{80} - \frac{104}{80} = \frac{106}{80}$

д)

$2 \frac{13}{14} - 1 \frac{20}{21} = \frac{41}{14} - \frac{41}{21} = \frac{123}{42} - \frac{82}{42} = \frac{41}{42}$

е)

$8 \frac{19}{20} - 3 \frac{7}{30} = \frac{179}{20} - \frac{97}{30} = \frac{537}{60} - \frac{194}{60} = \frac{343}{60}$
