Question

Answer 1

`5/9 : 4/7 + 13/9 × 7/4`

`= 5/9 × 7/4 + 13/9 × 7/4`

`= ( 5/9 + 13/9 ) × 7/4`

`= 2 × 7/4`

`= 7/2`

Answer 2

` 5/9 : 4/7 + 13/9 xx 7/4`

` = 5/9 xx 7/4 + 13/9 xx 7/4`

` = 7/4 xx ( 5/9 + 13/9)`

` = 7/4 xx 2`

` = 7/2`

Answer 3

\(=\dfrac{5}{9}\cdot\dfrac{7}{4}+\dfrac{13}{9}\cdot\dfrac{7}{4}=\dfrac{7}{4}\cdot2=\dfrac{7}{2}\)
