Answer 6

rational numbers are `that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero`
irrational are that cannot be `expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero`

4/5 is already expressed thus rational.
sqrt2=1.4142135623730950488016887242097....... cannot be expressed thus irrational
2.5, 0.4 are also expressed already. thus also rational.
sqrt16=4 thus rational.
