Answer»

According to commutative property of addition

If a and b are two rational numbers Then,a + b = b + a

(i) - 4/3 and 3/7-4/3 + 3/7 = (-28 + 9)/7 = - 19/73/7 + - 4/3= (9 - 28)/7 = - 19/7

(ii)-2/-5 and 1/32/5 + 1/3 = (6 + 5)/15 = 11/151/3 + 2/5 = (5 + 6)/15 = 11/15

(iii)9/11 and 2/139/11 + 2/13 = (117+22)/143= 139/1432/13 + 9/11 = (22 + 117)/143= 139/143
