Resposta:
Vamos calcular as operações:
A) 2/9 + 5/9 = (2 + 5)/9 = 7/9
B) 5/6 - 2/6 = (5 - 2)/6 = 3/6 = 1/2
C) 3/4 + 1/5 = (15/20 + 4/20) = 19/20
D) 7/8 - 4/9 = (63/72 - 32/72) = 31/72
E) 1/7 + 3/5 + 9/14 = (2/14 + 6/14 + 9/14) = 17/14 = 1 3/14
F) 3 - 14/5 = (15/5 - 14/5) = 1/5
G) 1 2/11 + 7/10 = 11/11 + 14/11 = 25/11
H) 2 1/5 - 1/6 = (10/5 + 1/5 - 1/6) = 10/5 + 5/5 - 5/30 = 15/5 - 1/30 = 3 - 1/30
I) 7 + 2/9 = 63/9 + 2/9 = 65/9
J) 3/4 - 1/6 = (9/12 - 2/12) = 7/12
K) 1/5 + 2 + 7/8 = (1/5 + 10/5 + 35/8) = 46/5 + 35/8
L) 3 2/5 - 1/7 = (17/5 - 1/7) = (119/35 - 5/35) = 114/35
