в)3 1/2-1 2/3

Answer 1

А) 6 2/5-1 1/10=6 4/10-1 1/10=5 3/10

Б) 4 5/7-1 2/3=4 15/21-1 14/21=3 1/21

В) 3 1/2-1 2/3=3 3/6-1 4/6=2 9/6-1 4/6=1 5/6

Answer 2

а) $6 \frac{2}{5} - 1 \frac{1}{10} = 6 \frac{4}{10} - 1 \frac{1}{10} = 5 \frac{3}{10} = 5.3$
б) $4 \frac{5}{7} - 1 \frac{2}{3} = 4 \frac{15}{21} - 1 \frac{14}{21} = 3 \frac{1}{21}$
в) $3 \frac{1}{2} - 1 \frac{2}{3} = 3 \frac{3}{6} - 1 \frac{4}{6} = 1 \frac{5}{6}$
