Question

2/5 x 1/2 : 1/3. 2/9 : 2/3 x 1/2

Answer 1

`2/5 xx 1/2 : 1/3`

`= 2/10 xx 3`

`= 6/10`

`= 3/5`

`---`

`2/9 : 2/3 xx 1/2`

`= 2/9 xx 3/2 xx 1/2`

`= 6/18 xx 1/2`

`= 1/3 xx 1/2`

`=1/6`

Answer 2

\(\dfrac{2}{5}.\dfrac{1}{2}:\dfrac{1}{3}=\dfrac{2}{10}:\dfrac{1}{3}=\dfrac{6}{10}=\dfrac{3}{5}\\ \dfrac{2}{9}:\dfrac{2}{3}\times\dfrac{1}{2}=\dfrac{1}{3}\times\dfrac{1}{2}=\dfrac{1}{6}\)

Answer 3

\(\dfrac{2}{5}\times\dfrac{1}{2}\div\dfrac{1}{3}=\dfrac{1}{5}\div\dfrac{1}{3}=\dfrac{3}{5}\)

`----`

\(\dfrac{2}{9}\div\dfrac{2}{3}\times\dfrac{1}{2}=\dfrac{1}{3}\times\dfrac{1}{2}=\dfrac{1}{6}\)
