i. If $x=y$ and $y=3$ , then $x=3$ .

ii. If $n$ is a natural number, then $n$ is an integer.

iii. If all three sides of a triangle are equal, then the triangle is equilateral.

iv. If $x$ and $y$ are negative integers, then $xy$ is positive.

v. If a natural number $n$ is divisible by 6, then $n$ is divisible by 2 and 3.
