Answer 1

a, \(\dfrac{1}{2}.\dfrac{1}{4}.\dfrac{1}{6}=\dfrac{1}{48}\)

b, \(\dfrac{1}{2}.\dfrac{1}{4}:\dfrac{1}{6}=\dfrac{1}{8}.6=\dfrac{6}{8}=\dfrac{3}{4}\)

Answer 2

\(a,\dfrac{1}{2}\times\dfrac{1}{4}\times\dfrac{1}{6}=\dfrac{1}{8}\times\dfrac{1}{6}=\dfrac{1}{48}\)

\(b,\dfrac{1}{2}\times\dfrac{1}{4}:\dfrac{1}{6}=\dfrac{1}{8}:\dfrac{1}{6}=\dfrac{6}{8}=\dfrac{3}{4}\)
