Answer 1

\(\dfrac{1}{2}-\dfrac{3}{2}\cdot\dfrac{4}{9}=\dfrac{1}{2}-\dfrac{2}{3}=-\dfrac{1}{6}\)

Answer 2

\(\dfrac{1}{2}-\dfrac{3}{2}.\dfrac{4}{9}=\dfrac{1}{2}-\dfrac{3.2.2}{2.3.3}=\dfrac{1}{2}-\dfrac{2}{3}=\dfrac{3}{6}-\dfrac{4}{6}=-\dfrac{1}{6}\)

Answer 3

\(\dfrac{1}{2}-\dfrac{3}{2}.\dfrac{4}{9}\)

= \(\dfrac{1}{2}-\dfrac{2}{3}\)

= \(\dfrac{3}{6}-\dfrac{4}{6}\)

=\(\dfrac{-1}{6}\)

Answer 4

`1/2 - 3/2 xx 4/9`

`= 1/2 - 2/3`.

`= -1/6.`
