Răspuns:
A) =36/29-56/17+254/29-131/17
= 290/29-187/17
B) = 0,12-8,23+0,88-3,77
= - 8,11-2,89
= - 11
C) =( - 31/13-105/11)+(-60/11 - 99/13)
= - 31/13-105/11-60/11-99/13
= 130/13 - 165/11
D) = 11/18+6/27+7/18-5/36
= 18/18 amplificam cu 6 + 6/27 amplificam cu 4 - 5/36 amplificam cu 3
= 108/108 + 24/108 - 15/108
= 117/108
