Răspuns

a) 1;

b) 13/7;

c)  1/13;

d)   1/3;

Explicație pas cu pas:

a) (7/8 - 1/8) + 1/4 = 6/8 + 1/4 =6/8 + 2/8 = 8/8 = 1;

b) (5/6 + 7/6) - 1/7 = 12/6 - 1/7 = 2 - 1/7 = 14/7 - 1/7 = 13/7;

c) (7/3 - 4/3 )- 12/13 = 3/3 - 12/13 = 1 - 12/13 = 13/13 - 12/13 = 1/13;

d)  4/3 - (9/11 + 2/11) = 4/3 - 11/11 = 4/3 - 1 = 4/3 - 3/3 = 1/3;
