Answer 4

`-2/9 + 8/15 + 1 `2/3`- 7/9 + -7/15`

=`-2/9 + 8/15 + 5/3 - 7/9 + -7/15`

=`(-2/9 - 7/9) + (8/15 + 7/15) + 5/3`

= `-9/9 + 15/15 + 5/3`

=`-1 + 1 + 5/3`

= `0 + 5/13`

= `0`

Answer 5

`-2/9 + 8/15 + 1 2/3- 7/9 + -7/15`

`=-2/9 + 8/15 + 5/3 - 7/9 + -7/15`

`=(-2/9 - 7/9) + (8/15 + 7/15) + 5/3`

`= -9/9 + 15/15 + 5/3`

`=-1 + 1 + 5/3`

= `0 + 5/13`

`=5/13`
