The points P, Q, R, S, T, U and V on the number line such that, US=SV=VR, and WT=TP=PQ. The rational number represented by P.

The points P, Q, R, S, T, U and V on the number line such that, US=SV=VR, and WT=TP=PQ. The rational number represented by V.

The points P, Q, R, S, T, U and V on the number line such that, US=SV=VR, and WT=TP=PQ. The rational number represented by W.

Find the vlaues of P,Q,R,S and T on the given number line.

Let O, P and Z represent the numbers 0, 3 and -5 respectively on the number line. Points Q, R and S are between O and P such that OQ = QR = RS = SP. What are the rational numbers represented by the points Q, R and S. Next choose a point T between Z and O so that ZT = TO. Which rational number does T represent?

In P Q R , S is any point on the side Q R . Show that P Q+Q R+R P >2P S
