Answer 1

Step-by-step explanation:

-3/7+x=4/9

x-3/7=4/9

x-27-28/63

x-55/63

63x-55=0

x=55/63 OK friend

Answer 2

let the number to be added be x

therefore ,

1. -3/7 +x= 4/9
2. x = 4/9 + 3/7
3. x = 28/63 + 27/63 (LCMof 9and7 is 63)
4. x= 55/63
5. x= 55 /63
6. therefore, 55/63 must be added to -3/7 to get 4/9
