The points P, Q, R, S, T, U, A and B on the number line are such that, TR = RS = SU and AP = PQ = QB. Name the rational numbers represented by P, Q, R and S.
Here,
Distance between U and T is 1 unit
And,
It is divided into three equal parts.
That are:
TR = RS = SU = 
Thus,
R = 
= 
= 
S =
= 
= 
In the same way,
AB = 1 unit
And,
It is divided into three equal parts.
P = 
= 
= 
Q= 
= 
=
