Question

Question 6 Let m and n be positive integers. Let mRn is a relation on positive integers such that m | n (meaning that m divides n). Show that whether the relation Ris equivalence or not. You must explain your answer. An answer without explanation would get only 1 point. ттт Anai 3(12pt)

Answer 1

As per rule 1 question is solved at a time

Q6)

Since for any positive integer we have
m m
( I.e every positive integer divides itself)

So the relation is reflexive.

We know that  $6=2\times 3$ so $2\text{ R }6$ ( 2 divides 6), but 6 does not divide 2. So $6 ~\not\text{R}~2$

So the relation is not symmetric

Hence, it can not be an equivalence relation.
