Question

1/2 hay 2/3 lớn hơn

Answer 1

1/2=3/6

2/3=4/6

=>1/2<2/3

=>2/3 lớn hơn

Answer 2

MSCNN là : 6

1/2 x 3 = 3/6

2/3 x 2 = 4/6

3/6 < 4/6 thì 1/2 < 2/3 nên 2/3 lớn hơn

Answer 3

ta có :

`1/2= (1xx3)/(2xx3)=3/6`

`2/3=(2xx2)/(3xx2)=4/6`

mà `3/6 < 4/6=>1/2<2/3`

nên `2/3` lớn hơn

Answer 4

\(\dfrac{1}{2}=\dfrac{3}{6};\dfrac{2}{3}=\dfrac{4}{6}\)

\(\Rightarrow\dfrac{3}{6}< \dfrac{4}{6}\Rightarrow\dfrac{1}{2}< \dfrac{2}{3}\)
