d) 8/3 + 5/3 = __________
e) 5/12 + 7/12 = ________
f) 4/10 + 3/10 = ________
g) 12/5 + 4/5 = _________
h) 5/6 + 3/6 = __________
i) 1/2 + 3/2 = __________

Answer 1

Vamos lá :

b) 6/9 + 5/9 = (6 + 5)/9 = 11/9

c) 1/4 + 2/4 = (1 + 2)/4 = 3/4

d) 8/3 + 5/3 = (8 + 5)/3 = 13/3

e) 5/12 + 7/12 = (5 + 7)/12 = 12/12 = 1

f) 4/10 + 3/10 = (4 + 3)/10 = 7/10

g) 12/5 + 4/5 = (12 + 4)/5 = 16/5

h) 5/6 + 3/6 = (5 + 3)/6 = 8/6

i) 1/2 + 3/2 = (1 + 3)/2 = 4/2 = 2

Espero ter ajudado !!!
