Answer 2

Answer:

sum of two rational no= 3/5

one no = -2/7

other no =?

so, -2/7+ ? = 3/5

let the other no be x

-2/7+x=3/5

x=3/5-(-2/7)

x=3/5+2/7

x= 21+10/35

x=31/35

the other no or x is 31/35

let's check ;

-2/7+31/35=3/5

-10+31/35=3/5

21/35=3/5

3/5=3/5

both r same u can check , I have given the ans and also I have checked it once to prove and I have proved.
