Answer:
3/7 +2/5
First find LCM
LCM=35 ( we have to multiply the denominators are there is no common factor between 5 and 7)
The make denominators same by multiplying numerator & denominator by same number.
3/7 x 5/5 = 15/35 ; 2/5 x 7/7 = 14/35
Add them,
15/35 + 14/35= 29/35 (its in lowest term already because there is no common factor between 29 & 35)
Now,
29/35 is a rational number.
Hence closure property is verified
