Hey Mate !! Here's your answer !! Taking LCM we get 72 as the denominator. So -31 / 72 must be added.

Answer:

Let the unknown number be denoted by ' x '

So when this is added to 7 / 8 we get 4 / 9

So we must find the value of  x  

Procedure :

= x + 7 / 8 = 4 / 9

= x = 4 / 9 - 7 / 8

Taking LCM we get 72 as the denominator.

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

= x = 32 - 63 / 72

= x = ( -31 ) / 72

So -31 / 72 must be added.

Hope this helps !
