Answer 1

Ello mate, Here are all your answers !

Step-By-Step-Explanation:

Answer 1 :
`4(1)/(2)`

Answer 2 :
`8(8)/(5)`

Answer 3 :
`3(1)/(3)`

Answer 2

1.Option D

2.Option B

3.Option D

Explanation:

1.We are given that
`1(1)/(3)+2(3)/(4)`

We have add and simplify

`(4)/(3)+(11)/(4)`

`1(1)/(3)+2(3)/(4)`=
`(16+33)/(12)`

`1(1)/(3)+2(3)/(4)`=
`(49)/(12)`

`1(1)/(3)+2(3)/(4)=(49)/(12)`

Hence, Option D is true.

2.We are given that
`11(1)/(12)-2(2)/(3)`

We have to subtract and simplify

`(133)/(12)-(8)/(3)`

=
`(133-32)/(12)`

=
`(101)/(12)`

`8(5)/(12)`

Hence,option B is true.

3.We are given that
`1(3)/(12)\cdot 2(2)/(3)`

We have to multiply and simplify

`(15)/(12)\cdot(8)/(3)`

=
`(5)/(12)\cdot 8`

=
`(10)/(3)`

=
`3(1)/(3)`

Hence, option D is true.
