Answer 3

`8/3 + 6/7`

`=56/21 + 18/21`

`= 74/21 `

`8/3 - 5/12`

`= 32/12 - 5/12 = 27/12`

`= 9/4`

Answer 4

`8/3 + 6/7`

`=56/21 + 18/21`

`= 77/21 = 11/3`

`8/3 - 5/12`

`= 32/12 - 5/12 = 27/12`

`= 9/4`

Answer 5

`8/3 + 6/7 = 56/21 + 18/21 = (56 + 18)/21 = 74/21`

_____________________________________________

`8/3 - 5/12 = 32/12 - 5/12 = (32-5)/12 = 27/12`
