Answer 2

Answer:

To find a rational number between two numbers, we should find LCM first.

LCM of 2/5 & 1/2 = 10

2/5 is converted to 4/10

1/2 is converted to 5/10

if there are no numbers between 4/10 and 5/10 multiply them with any number (like 3)

4*3/10*3 = 12/30

5*3/10*3 = 15/30

rational number between is 13/30 or 14/30.
