Question

2)calcule as operações e simplifique o resultado quando possível.
A)1/2+3/2=
B)5/3+4/3=
C)4/6-1/6=
D)7/5-2/5
E)3/4+1/ =
F)5/6-3/4=
G)1/2-/1/3-1/6=
H)3/2-2/3=
I)1/3+4/6=
J)1/2+1/3+1/5=
K)3/2+1/3+1/5=
L)4/6-1/3=

Answer 1

A)1/2+3/2= 4/2 = 2

B)5/3+4/3= 9/3 = 3

C)4/6-1/6= 3/6 = 1/3

D)7/5-2/5 = 5/5 = 1

E)3/4+1/ = está faltando o denominador

F)5/6-3/4, mmc = 12

10/12-9/12 = 1/12

G)1/2-1/3-1/6, mmc = 6

3/6-2/6-1/6

3/6-3/6 = 0

H)3/2-2/3, mmc = 6

9/6-4/6 = 5/6

I)1/3+4/6, mmc = 6

2/6+4/6

6/6 = 1

J)1/2+1/3+1/5, mmc = 30

15/30+10/30+6/30 = 31/30

K)3/2+1/3+1/5, mmc = 30

45/30+10/30+6/30 = 61/30

L)4/6-1/3, mmc = 6

4/6-2/6

2/6 = 1/3
