Ответ:

1)= (3 19/24 + 1 5/24) + 5 1/9 = 4 24/24 + 5

1/9 = 5 + 5 1/9 =10 1/9:

2)= (15/8 + 2 3/8) + (4 8/17 + 9/17) = 3 8/8 + 4

17/17 = 4 + 5 = 9 ;

3)= (716/35 - 3 11/35) - 4 1/56 = 4 5/35 - 4

1/56 = 4 1/7 - 4 1/56 = 4 8/56 - 4 1/56 = 7/56 = 1/8 ;

4)= (4 56/789 - 4 56/789) + 1 23/456 = 0 + 1

23/456 = 123/456
