\(\dfrac{1}{2}=\dfrac{1.3}{2.3}=\dfrac{3}{6}>\dfrac{1}{6}\)
=>\(\dfrac{1}{2}>\dfrac{1}{6}\)
\(MSC:6\\ \dfrac{1}{2}=\dfrac{1\times3}{2\times3}=\dfrac{3}{6};\dfrac{1}{6}\\ 3>1\\ \Rightarrow\dfrac{1}{2}>\dfrac{1}{6}\)
\(\dfrac{1}{2}vs\dfrac{1}{6}MSC:6\)
\(\dfrac{1}{2}=\dfrac{1x3}{2x3}=\dfrac{3}{6}\)
mà: 3 >1
vậy \(\dfrac{3}{6}>\dfrac{1}{6}\)
