Answer 2

`1(5)/(12)`

Explanation:

`(2)/(3) + (9)/(12)` <-- let's change 2/3 into a fraction that has 12 as the denominator

`(2)/(3)` × 4 <-- multiply both the numerator and the denominator by 4

2 × 4 = 8 <-- new numerator

3 × 4 = 12 <-- new denominator

now we have
`(8)/(12)` +
`(9)/(12)`

`(8)/(12)` +
`(9)/(12)` =
`(17)/(12)` <-- let's change it into a mixed number

17 ÷ 12 =
`1(5)/(12)`
