\(\dfrac{1}{2}+\dfrac{4}{3}\times\dfrac{1}{6}=\dfrac{1}{2}+\dfrac{4}{18}=\dfrac{9}{18}+\dfrac{4}{18}=\dfrac{13}{18}\)
\(\dfrac{1}{2}+\dfrac{4}{3}\times\dfrac{1}{6}\)
\(=\dfrac{1}{2}+\left(\dfrac{4}{3}\times\dfrac{1}{6}\right)\)
\(=\dfrac{1}{2}+\dfrac{4}{18}\)
\(=\dfrac{1}{2}+\dfrac{2}{9}=\dfrac{9}{18}+\dfrac{4}{18}=\dfrac{13}{18}\)
1/2 + 4/3 x 1/6
=1/2 + 4/18
= 1/2 + 2/9
= 9/18 + 4/18
=13/18
