Please help me answer this question its urgent

Answer 1

Explanation:

1).
`(2)/(3)n-(3)/(4)n+(1)/(6)n+2(2)/(9)n`

=
`(2)/(3)n-(3)/(4)n+(1)/(6)n+(2+(2)/(9))n`

=
`((2)/(3)-(3)/(4)+(1)/(6))n+(2+(2)/(9))n`

=
`((8)/(12)-(9)/(12)+(2)/(12))n+(2+(2)/(9))n`

=
`((8-9+2))/(12)n+(2+(2)/(9))n`

=
`(1)/(12)n+(2+(2)/(9))n`

=
`((1)/(12)+2+(2)/(9))n`

=
`((3)/(36)+(72)/(36)+(8)/(36))n`

=
`(83)/(36)n`

=
`2(11)/(36)n`

2).
`(2)/(5)g-(1)/(6)-g+(3)/(10)g-(4)/(5)`

=
`((2)/(5)-1+(3)/(10))g-((1)/(6)+(4)/(5))`

=
`((4)/(10)-(10)/(10)+(3)/(10))g-((5)/(30)+ (24)/(30))`

=
`((4-10+3)/(10))g-((5+24)/(30))`

=
`(-3)/(10)g-(29)/(30)`

=
`-(3)/(10)g-(29)/(30)`

3).
`i+6i-(3)/(7)i+(1)/(3)h+(1)/(2)i-h+(1)/(4)h`

=
`7i-(3)/(7)i+(1)/(2)i+(1)/(3)h-h+(1)/(4)h`

=
`(7-(3)/(7)+(1)/(2))i+((1)/(3)-1+(1)/(4))h`

=
`((98)/(14) -(6)/(14)+(7)/(14))i+((4)/(12)-(12)/(12)+(3)/(12))h`

=
`((98-6+7)/(14))i+((4-12+3)/(12))h`

=
`(99)/(14)i-(5)/(12)h`
