Answer 1

Ответ:

Пошаговое объяснение:

а)6/19 - 3/19 + 15/19 = (6-3+15)/19 = 18/19

б)19/21 - 17/21 + 9/21 = (19-17+9)/21 = 11/21

в)25/32 - 6/32 + 19/32 = (25-6+19)/32 = 38/32 = 1 6/32 = 1 3/16

Answer 2

Ответ:

$\frac{6}{19} - \frac{3}{19} + \frac{15}{19} = \frac{18}{19} \\ \frac{19}{21} - \frac{17}{21} + \frac{9}{21} = \frac{11}{21} \\ \frac{25}{32} - \frac{6}{32} + \frac{19}{32} = \frac{38}{32} = 1 \frac{6}{32} = 1 \frac{3}{16}$
