(i)

Let suppose,

As we can see that a ˂ b

So, the rational number lying between a and b

So, we can say that is a rational number lying between 1/4 and 1/3.

(ii)

Let’s take

As we can see a˂b

A rational number lying between

is the number lying between

(iii) 1.3 and 1.4

By taking a = 1.3 and b = 1.4

As we can see a ˂ b

Rational number between a and b,

1.35 is the number lying between 1.3 and 1.4

(iv) 0.75 and 1.2

Let’s take a = 0.75 and b = 1.2

As we can see a˂b,

Rational number between a and b,

0.975 is the number between 0.75 and 1.2

(v)

Let’s take

Rational number between a and b,

is the number between -1 and

(vi)

Let’s take

Rational number between a and b,

So, rational number between
