Question

Answer 1

`a, 1/3 . (4/5 +6/5)`

`= 1/3 xx 2`

`= 2/3`.

`b, = 27/182 - 1/182`

`= 1/7`

`c, 15 . (1/5 - 7/15)`

`= 15 . -4/15`

`= -4`

Answer 2

a.

\(=\dfrac{1}{3}.\left(\dfrac{4}{5}+\dfrac{6}{5}\right)=\dfrac{1}{3}.\dfrac{10}{5}=\dfrac{10}{15}=\dfrac{2}{3}\)

Answer 3

`1/3 . 4/5 + 1.3 . 6/5`

`= 1/3 . ( 4/5 + 6/5)`

`= 1/3 . 10/5`

`= 1/3 . 2`

= 3.2`

____________________

`3/7 . 9/26 - 1/14 . 1/13`

`= 1/14 . 27/13 - 1/14 . 1/13`

`= 1/14 . (27/13 - 1/13)`

`= 1/14 . 26/13`

`= 1/14 . 2`

`= 2/14`

`= 1/7`
