It's 11
you need to add +9 +9-7 = +2
-9 + 11 = 2
2/9 + 2/3 = 2/9 + 6/9 = 8/9

nine add 7 to get from -7 to 0 then add 2 to get to 2 7 + 2 = 9

No. The digits of 4592 add to 4+5+9+2 = 20 The digits of 20 add to 2+0 = 2 2 is not divisible by 9, so 4592 is not.

Convert 2/3 to 6/9, then you can add the whole parts, and add the fractions, you will have: (9 + 2) + (6/9 + 7/9) = 11 + 13/9. 13/9 is the same as 1 4/9, so then you have 124/9.
No; because if you add 2+2+9+9+6, you get 28 and 9 can only go into 27, so no.
