Răspuns:
a) 1/4 + 5/4 = (1 + 5)/4 = 6/4 = 3/2
b) 23/17 + 11/17 = (23 + 11)/17 = 34/17 = 2/1 = 2
c) 16/93 + 15/93 = (16 + 15)/93 = 31/93 = 1/3
d) 11/14 + 23/14 = (11 + 23)/14 = 34/14 = 17/7
e) 3/16 + 15/16 = (3 + 15)/16 = 18/16 = 9/8
f) 1 1/8 + 1 3/8 = (1×8+1)/8 + (1×8+3)/8 = 9/8 + 11/8 = 20/8 = 5/2 = 2 1/2
g) si h) ti le las tie sa aprofundezi dupa modelele rezolvate de mine
Bafta !
