Question

4/5x3/7+4/5x6/7-4/5x4/14

Answer 1

`4/5 xx 3/7 + 4/5 xx 6/7 - 4/5 xx 4/14`

`= 4/5 xx (3/7 + 6/7 - 2/7)`

`= 4/5 xx 1`

`= 4/5`

Answer 2

= 4/5 x (3/7 + 6/7 - 4/14)

= 4/5 x (9/7 - 4/14)

= 4/5 x (18/14 - 4/14)

= 4/5 x 1

= 4/5

Answer 3

\(\dfrac{4}{5}.\left(\dfrac{3}{7}+\dfrac{6}{7}-\dfrac{4}{14}\right)\)

\(\dfrac{4}{5}.\left(\dfrac{3}{7}+\dfrac{6}{7}-\dfrac{2}{7}\right)\)

\(\dfrac{4}{5}.1=\dfrac{4}{5}\)
