Question

what should be added to -7/8 to get 4/9?

Answer 1

Answer: 95/72

Step-by-step explanation:

- 7/8  +  x  = 4/9

x = 4/9 - (-7/8)

x = 4/9 + 7/8

x = (4×8 + 7×9) / 72

x = 95/72

Answer 2

Answer:

95/72

Step-by-step explanation:

Let the unknown fraction be x,

-7/8 + x = 4/9

=> x = 4/9 + 7/8

=> x = 4*8 / 9*8 + 7*9 / 8*9 (Because the LCM of 8 and 9 is 72)

=> x = 32/72 + 63/72

=> x = 95/72

Therefore,

-7/8 + 95/72 = 4/9
