Answer:
Let other number is x .
( 4 ). x + (-1/3) = -12/3
Therefore, x = -12/3 +1/3 = -11/3 ANS.
(3). 1/3 +x = 5/9
x = 5/9 - 1/3 = (5- 3)/9 = 2/9 ANS.
(5). (-5)+x = -4/3
x = -4/3+5 = (-4+15)/5 = 11/5 Ans.
(6). -15/7 +x = -8
x = 15/7 -8 = (15- 56)/ 8 = -41/8 Ans.
(7). -7/8 +x = 5/9
x = 5/9 +7/8 = (40+63)/8 = 103/8 Ans.
(8). -5/11 + x = 26/33
x = 26/33+5/11 = (26 +15)/33 = 41/33 Ans.
