Question

calcule e simplifique os resultados quando for possivel (a) 1/2+2/3 (b) 5/6+2/3 (c) 4/5+2/3 (d) 2/5+1/10/+1/2 (e) 2/2+1/10+3/2

Answer 1

a)1/2+2/3 MMC (2,3)=6
3/6+4/6=7/6

b)5/6+2/3 MMC(6,3)=6
5/6+4/6=9/6 simplifica por 3= 3/2

c) 4/5+2/3 MMC (5,3)=15
12/15+10/15=22/15

d) 2/5+1/10+1/2 MMC (5,10,2)=10
4/10+1/10+5/10= 10/10 simplifica por 10=1

e) 2/2+1/10+3/2 MMC(2,10,2)=10
10/10+1/10+15/10=26/10 simplifica por 2= 13/5
Espero ter ajudado.

Answer 2

Resposta:

A) 3/6 + 4/6 = 7/6

B) 15/18 + 12/18 = 27/18 = 3/2

C) 12/15 + 10/15 = 22/15

D) 4/10 +  1/10 + 5/10 =10/10 =1

E) 4/70 + 1/70 + 6/70 = 11/70
