Объяснение:

2) 1 5/7 - 4 3/13 : 1 19/26 = - 46/63

1) 4 3/13 : 1 19/26 = 55/13 : 45/26 = 55/13 * 26/45 = 22/9 = 3 4/9

2) 1 5/7 - 3 4/9 = 12/7- 22/9 = 108/63 - 154/63 = - 46/63

4) 47/48 : 3 13/27 - 13/16 = - 17/32

1) 47/48 : 3 13/27 = 47/48 * 27/94 = 9/(16*2) = 9/32

2) 9/32 - 13/16 = 9/32 - 26/32 = - 17/32

Объяснение:

2)  1 5/7 + 4 3/13 : 1 19/26 = 1 5/7 - 55/13:45/26=1 5/7 - 55*26/13*45 =

=1 5/7 - 2 4/9=-(2 28/63) -1 45/63= -(91-45)/63 = -46/63.

4)  47/48:3 13/27 - 13/16 = 47/48 : 94/27 - 13/16 = 47/48 * 27/94 - 13/16=

=9/32 - 13/16 = 9/32 - 26/32 = -(26-9)/32= -17/32.
