A) Q is the subset of N

B) Q and N are overlapping sets

C) Q and N are disjoint sets

D) N is the subset of Q

2. What type Of fraction is 2/3

A) Recurring and terminating decimal fraction

C) Nonrecurring and non terminating decimal fraction

D) Nonrecurring and terminating decimal fraction

EVALUATION

ANSWER TO QUESTION : 1

Here

Q is the set of all real rational numbers and N is the set of all natural numbers

We know that every element of N is an element of Q but every element of Q is not an element of N

For example 0 ∈ Q but 0 ∉ N

So N is the subset of Q

Hence the correct option is

D) N is the subset of Q

ANSWER TO QUESTION : 2

Here the given number = 2/3

Now 2/3 = 0.66666...

So 2/3 has repeating decimal expansion

Hence the correct option is

B) Recurring and non terminating decimal fraction
