Answer 1

Given :-

A = (x : x is a natural number and a factor of 18)

B = (x : x is a natural number and less than 6)

Solution :-

Factors of 18 are 1, 2, 3, 6, 9, 18

A = {1, 2, 3, 6, 9, 18}

Natural number that is less than 6 are 1, 2, 3, 4, 5

B = {1, 2, 3, 4, 5}

Hence,

A ∪ B = {1, 2, 3, 4, 5, 6, 9, 18}

A ∩ B = {1, 2, 3}
