Answer 1

(I) -2/3 + 5/-7

solution : 5×-1/-7×-1 =-5/7

-2/3+(-5/7)

LCM of 3,7 = 21

-2×7/3×7=-14/21

-5×3/7×3=-15/21

-14/21+(-15/21)

-14/21-15/21

=-29/21

(ii) -1 1/12 + (-5/9)

solution: -13/12 +(-5/9)

LCM of 12,9 = 36

13×3/12×3=39/36

-5×4/9×4=-20/36

39/36+(-20/36)

39/36-20/36

19/36

(iii)2 2/5 + (-4 3/10)

solution: 12/5 +(-43/10)

LCM of 5,10 = 10

12×2/5×2=24/10

24/10+(-43/10)

24/10-43/10

=-19/10
