Răspuns:

Explicație pas cu pas:

a)

(4/15 + 11/15) + (9/10 + 41/10) = 15/15 + 50/10 = 1 + 5 = 6

b)

(17/16 + 15/16) + (12/13 + 14/13) = 32/16 + 26/13 = 2 + 2 = 4

c)

(5/8 + 3/8 + 1/8) + (7/18 + 11/18) = 9/8 + 18/18 = 9/8 + 1 = 9/8 + 8/8 = 17/8

d)

(8/14 + 5/14 + 1/14) + (1/3 + 2/3) = 14/14 + 3/3 = 1 + 1 = 2
