**1. **(i) -1 and 0

Let us write -1 and 0 as rational numbers with denominator 6.

Therefore, five rational numbers between -1 and 0 would be

(ii) -2 and -1

Let us write -2 and -1 as rational numbers with denominator 6.

Therefore, five rational numbers between -2 and -1 would be

let us write as rational numbers with the same denominators

Therefore, five rational numbers between would be

Let us write as rational numbers with the same denominators.

Therefore, five rational numbers between would be

Therefore, the next four rational numbers of this pattern would be

Therefore, the next four rational numbers of this pattern would be

Therefore, the next four rational numbers of this pattern would be

Therefore, the next four rational numbers of this pattern would be

Therefore, four equivalent rational numbers are

Therefore, four equivalent rational numbers are

**4. ** **5. ** Each part which is between the two numbers is divided into 3 parts.

Thus, the rational numbers represented P, Q, R and S are respectively.

**7. ** **8. ** (i) Since, the positive number if greater than negative number.

Since, 0 is greater than every negative number.

Since positive number is always greater than negative number.
