Answer 2

Answer:

9/10

Step-by-step explanation:

Let the number added be x.

So,

-7/5+x = -4/8

x = -4/8+7/5 (Shifting -7/5 from LHS to RHS)

x = -4×5/8×5+7×8/5×8 ( L.C.M = 40 )

x = -20/40+56/40

x = -20+56/40

x = 36/40

x = 18/20

x = 9/10 is the answer.

•°• So,

9/10 should be added to -7/5 to get -4/8.

( Note: We cannot add 0.9 because the question is in fraction. If we do our answer will be wrong )
