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

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

$5 - 2 \frac{5}{9} = \frac{45}{9} - \frac{23}{9} = \frac{22}{9} = 2\frac{4}{9}$

$2 \frac{5}{8} - 1 \frac{3}{10} = \frac{21}{8} - \frac{13}{10} = \\ = \frac{105}{40} - \frac{52}{40} = \frac{53}{40} = 1 \frac{13}{40}$

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

$8 \frac{19}{20} - 3 \frac{7}{30} = \frac{179}{20} - \frac{97}{30} = \\ = \frac{537}{60} - \frac{194}{60} = \frac{343}{60} = 5 \frac{43}{60}$

Ответ:

Пошаговое объяснение:

А) 1 - 5/6 = 6/6 - 5/6 = 1/6

Б) 8. 3/4 - 7. 5/6 = 8. 9/12 - 7. 10/12 = 7. 21/12 - 7. 10/12 = 11/12

В) 5 - 2. 5/9 = 4. 9/9 - 2. 5/9 = 2. 4/9

Г) 2. 5/8 - 1. 3/10 = 2. 25/40 - 1. 12/40 = 1. 13/40

Д) 2. 13/14 - 1. 20/21 = 2. 39/42 - 1. 40/42 = 1. 81/42 - 1. 40/42 = 41/42

Е) 8. 19/20 - 3. 7/30 = 8. 57/60 - 3. 14/60 = 5. 43/60
