Rational numbers are numbers that have an ending to them or repeat themselves, such as 0.675 or 0.
. Irrational numbers are numbers that have no ending and don't repeat themselves, such as pi.
____________________________________________________________
1) m = 2/3 = 0.
, n = √9 = 3
so 1 cannot be a choice.
2) m = 6/5 = 1.2, n = √2 = 1.41421356237...
so 2 can be a choice.
3) m = 4
= 12.5663706..., n = √5 = 2.2360679775...
so 3 cannot be a choice.
4) m = 6/2 = 3 (whole number, not rational), n =
= 1.57079633...
so 4 cannot be a choice.
