Question

\(\dfrac{5}{7}\)x\(\dfrac{5 }{11}\)\(+\dfrac{5}{7}\)\(\text{x}\dfrac{2}{11}\)\(-\dfrac{5}{7}\)\(\text{x}\dfrac{14}{11}\)

Answer 1

`5/7xx5/11+5/7xx2/11-5/7xx14/11`

`=5/7xx(5/11+2/11-14/11)`

`=5/7xx(-7/11)`

`=-5/11`

Answer 2

\(\dfrac{5}{7}\times\dfrac{5}{11}+\dfrac{5}{7}\times\dfrac{2}{11}-\dfrac{5}{7}\times\dfrac{14}{11}\)

=\(\dfrac{5}{7}\times\left(\dfrac{5}{11}+\dfrac{2}{11}-\dfrac{14}{11}\right)\)

=\(\dfrac{5}{7}\)\(\times-\dfrac{7}{11}\)

=\(-\dfrac{5}{11}\)
