Пошаговое объяснение:

1) 6 9/19 + 8 7/19  = ( 6 + 8 ) + ( 9/19 + 7/19 ) = 14 + 16/19 = 14 16/19

2) 35 11/41 - 13 8/41 = ( 35 - 13 ) + ( 11/41 - 8/41 ) =  22 + 3/41 = 22 3/41

Ответ:

[tex]6 \frac{9}{19} + 8 \frac{7}{19} = \frac{123}{19} + \frac{159}{19} = \frac{282}{19} = 14 \frac{16}{19} \\ 2)35 \frac{11}{41} - 13 \frac{8}{41} = \frac{1446}{41} - \frac{541}{41} = \frac{905}{41} = 22 \frac{3}{41} [/tex]
