Question

6) Calcule e se possivel, simplifique o resultado
a)9/5+5/6
b)3/7+1/8
c)1/2+1/3
d)5/12-1/3+2/6
e)1/6+1/7​

Answer 1

Resposta:

a) 79/30

b) 31/56

c) 5/6

d) 5/12

e) 13/42

Explicação passo-a-passo:

a) 9/5+5/6 =

mmc(5, 6)=30

(54+25)/30 =

79/30

b) 3/7+1/8 =

mmc(7, 8)=56

(24+7)/56 =

31/56

c) 1/2+1/3 =

mmc(2, 3)=6

(3+2)/6 =

5/6

d) 5/12-1/3+2/6 =

mmc(12, 3, 6) = 12

(5-4+4)/12 =

5/12

e) 1/6+1/7​ =

mmc(6, 7)=42

(7+6)/42=

13/42
