-7/21 and 3/9
⇒ -7/21 = -1/3 and 3/9 = 1/3
∵ -1/3 ≠ 1/3
∴ -7/21 ≠3/9
Each part which is between the two numbers is divided into 3 parts. Therefore, A= 6/3, P=7/3, Q=8/3 and B=9/3 Similarly T=-3/3, R=-4/3, S=-5/3 and U = -6/3 Thus, the rational numbers represented P, Q, R and S are 7/3, 8/3, -4/3 and -5/3 respectively.
