Question

me ajudem ...a)2/4+2/2= b) 3/6-1/5= c)1/4+1/3= d) 1/6-1-2=

Answer 1

a)2/4 + 2/2 =

m.m.c = 4

2/4 + 4/4 = 6/4 simplificando por 2 = 3/2

b)3/6 - 1/5 =

m.m.c = 30

15/30 - 6/30 = 9/30 simplificando por 3 = 3/10

c)1/4 + 1/3 =

m.m.c = 12

3/12 + 4/12 = 7/12

d)1/6 - 1/2 =

m.m.c = 6

1/6 - 3/6 = -2/6  simplificando por 2 = - 1/3
