Question

Answer 1

`1/3 - 2/15 + 14/15`

`= 5/15 - 2/15 + 14/15`

`=(5-2+14)/15`

`= 17/15`

`-----`

`3/5+4-6/7`

`= 3/5 + 20/5 - 6/7`

`= 23/5-6/7`

`= 131/35`

Answer 2

a) \(\dfrac{1}{3}\) - \(\dfrac{2}{15}\) + \(\dfrac{14}{15}\)                              b) \(\dfrac{3}{5}\) + 4 - \(\dfrac{6}{7}\)

=      \(\dfrac{1}{5}\)      + \(\dfrac{14}{15}\)                             =       \(\dfrac{23}{5}\) - \(\dfrac{6}{7}\)

=            \(\dfrac{17}{15}\)                                   =           \(\dfrac{131}{35}\)
