Пошаговое объяснение:
(2 7/14 - 5 9/32)+ ( 6 11/24 - 7 23/32)=- 4 13/48
1) 2 7/14 - 5 9/32= 2 (7*16)/224 - 5 (9*7)/224=2 112/224 - 5 63/224=-3 49/224=
- 3 7/32
2) 6 11 /24 - 7 23/32=6 (11*4)/96 - 7 (23*3)/96=6 44/96- 7 49/96=-1 -5/96=
-1 5/96
3) -3 7/32 + (- 1 5/96)= -3 (7*3)/96 - 1 5/96=- 3 21/96- 1 5/96=-4 26/96=
-4 13/48
