3 6/7×1 8/9
3 9/10:1 13/20
решить ​

Answer 1

Пошаговое объяснение:

$\frac{19}{20} - \frac{4}{15 } = \frac{41}{60} \\ 8 - \frac{5}{17} = \frac{131}{17} \\ 3 \times \frac{6}{7} \times 1 \times \frac{8}{9} = \frac{51}{7} \\ 3 \times \frac{9}{10} \div 1 \times \frac{13}{20} = 6 \times \frac{87}{200}$
