Răspuns:

1. introducem întregii in fractie: formula= a b/c= a×c+b/c

3 1/2 = 3×2+1= 7/2

2 1/3 = 2×3+1= 7/2

9 1/2=9×2+1=19/2

2 9/10 = 2×10+9= 29/10

6 3/5= 6×5+3= 33/5

rezolvare:

(7/2 + 7/2 ) : [(19/2 - 29/10): 33/5]

14/2 : ( 19\2×5 -29/10) ×5/33

14/2 : (95/10-29/10)× 33/5

14/2. : 66/10 ×33/5

14/2× 10/66 × 33/5

140/132× 33/5

4620/ 264

simplificam cu 4

= 1155/ 66

simplificam cu 3

=385/22

simplificam cu 11
