18-9/14=
40-2/11=
141-43/61

Answer 1

Ответ:

$8 - \frac{4}{7} = 7 \frac{7}{7} - \frac{4}{7} = 7 \frac{3}{7}$

$18 - \frac{9}{14} = 17 \frac{14}{14} - \frac{9}{14} = 17 \frac{5}{14}$

$40 - \frac{2}{11} = 39 \frac{11}{11} - \frac{2}{11} = 39 \frac{9}{11}$

$141 - \frac{43}{61} = 140 \frac{61}{61} - \frac{43}{61} = 140 \frac{18}{61}$

Answer 2

Ответ:

$8 - \frac{4}{7} =7 \frac{7}{7} - \frac{4}{7} = 7 \frac{3}{7} \\ 18 - \frac{9}{14} = 17 \frac{14}{14} - \frac{9}{14} = 17 \frac{5}{14} \\ 40 - \frac{2}{11} = 39 \frac{11}{11} - \frac{2}{11} = 39 \frac{9}{11} \\ 141 - \frac{43}{61} = 140 \frac{61}{61} - \frac{43}{61} = 140 \frac{18}{61}$
