Я весь номер напишу =)
1) 5 59+3 16 -6 427= 5 30/54+3 9/54-6 8/54=2 31/54

2)1 57+3 1114-2 14=1 10/14+3 11/14-2 14=4 21/14-2 14=4 3/2 -2 1/4=
  =5 1/2-2 1/4=5 2/4-2 1/4=3 1/4

3)12 1348-(9 1732-4 524)=12 1348-9 1732+4 524=
   =12 2696-9 5196+4 2096=7 - 5/96=6 91/96

4)(18-10 1835)-(3 928+2 3 20)=7 17/35-3 928-2 3 20=
=7 68/140-3 45/140-2 21/140=2 2/140=2 1/70
