##### Solution :-

Explanation:-

A rational number is represented by the form $$\dfrac{p}{q}$$ where p and q are integers and (q not equal to 0) keeping q = 1 we can place any number as p. Which then will be an integer.

Explanation:-

Crows are also birds, so they are contained in the set of all birds.

Explanation:-

Every square can be a rectangle, but every rectangle cannot be a square.

Explanation:-

Every square can be a rectangle, but every rectangle cannot be a square.

Explanation:-

P = {a}

B = {{a}}

But {a} = P

B = {P}

Hence they are not equal.

Explanation:-

A = For “LITTLE”

A = {L, I, T, E} = {E, I, L, T}

B = For “TITLE”

B = {T, I, L, E} = {E, I, L, T}

A = B
