Question

What should be added to (-2/7) to get 13/14​

Answer 1

x = 13/4 - (- 2/7)

x= 99/28

ANSWER:- 99/28

Answer 2

Answer:

9/14 or 0.643

Step-by-step explanation:

let the number be x

hence , ( - 2 / 7 ) + x = 13/14

hence , x = 13 / 14 + ( - 2 / 7 )

hence  , x = 13 / 14 - 2 / 7

hence , x = 13 / 14 - 4 / 14            ( take L.C.M of 7 and 14 which is 14 )

hence , x = 9 / 14 or 0.643
