Question

What number should be added to:-
i) -5/11 to get 5/9?
ii) -7/9 to get -9/11?
iii) 6/13 to get -7/26?​

Answer 1

Answer:

let required number be x

1) -5/11 + x = 5/9

x = 5/9+5/11

x = 1

2) -7/9 + x = -9/11

x = -9/11+7/9

x = -4/99

3) 6/13+x = -7/26

x = -7/26-6/13

x = -19/26

Answer 2

Answer:

i. -5/11 = 5/9

= 5/9 + 5/11

= 55/99 + 45/99

= 100/99

ii. -7/9 = -9/11

= -9/11 + 7/9

= -99/99 + 77/99

= -22/99 or -2/9

iii. 6/13 = -7/26

= -7/26 -6/13

= -7/26 -12/26

= -19/26
