b). 4/5+1/20=
c). 7/10+3/100=
d).7/6+5/12=
d).9/10+2/5=
e). 2/3+1/27=

Answer 1

a)1/8+1/4=2/12=3/2 (deoarece am simplificat cu 6)
b)4/5+1/20=5/25=1/5 (deoarece am simplificat cu 5)
c)7/10+3/100=10/110
d)7/6+5/12=12/18=4/6 (deoarece am simplificat cu 3)
e)9/10+2/5=11/15
f)2/3+1/27=3/30=1/10 (deoarece am simplificat cu 3)

Answer 2

a) 1/8 +1/4 = 1/8 +2/8 =3/8
b) 4/5 + 1/20 = 16/20 +1/20=17/20
c) 7/10 + 3/100 = 70/100 + 3/100 = 73/100
d) 7/6 + 5/12 = 14/12 + 5/12 = 19/12
d) 9/10 + 2/5 = 9/10 + 4/10= 13/10
e) 2/3 + 1/27 = 18/27 + 1/27 = 19/27
