Answer 2

Step-by-step explanation:

let the 2 fractions be a, b

case 1:

let their sum =x=a+b, difference =y=a-b

let adding sum to the difference be z= x+y

=> z= a+b+a-b = 2a

given a= 1⅔ , b=2 ⅝

z=2a= 2×1⅔ = 2× 5/3=10/3

case2:

difference can be y= b-a

then z= a+b+b-a =2b =2×2⅝

= 2×21/8=21/4
