Efetue as adições,
simplificando as frações
quando possível.
a) 3/2 + 2/3.
b) 1/3 + 4/6.
c) 3/4 + 5/6.
d) 1/2 + 1/3 + 1/5​

Answer 1

Resposta:

a) 3/2 + 2/3 = 5/5 = 1

b) 1/3 + 4/6 = 5/9

c) 3/4 + 5/6 = 8/10(simplificando por 2) = 4/5

d) 1/2 + 1/3 + 1/5 = 3/10

Answer 2

Resposta:

a)3/2 + 2/3 = 9/6 + 4/6 = 13/6

b)1/3 + 4/6 = 2/6 + 4/6 = 6/6 = 1

c)3/4 + 5/6 = 9/12 + 10/12 = 19/12

d)1/2 + 1/3 + 1/5 = 15/30 + 10/30 + 6/30 = 31/30
