Hey Mate !!
Here's your 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 !!
Cheers !!
