What i will the st either s minus t or s to t. please help. 1/4 1/3 4/3 3 4 PLEASE FORMAT THE QUESTIONS PROPERLY!Also what do you mean by "What i will the st either s minus t or s to t"? Original question is: On the number line, if r<s, if p is halfway between r and s, and if t is halfway between p and r then (st)/(tr)=A. 1/4 B. 1/3 C. 4/3 D. 3 E. 4 Let r=0 and s=4 > p is halfway between r and s: p=2; t is halfway between p=2 and r=0: t=1; (st)/(tr)=(41)/(10)=3. Answer: D. P.S. On the GMAT we can often see such statement: \(k\) is halfway between \(m\) and \(n\) on the number line. Remember this statement can ALWAYS be expressed algebraically as: \(\frac{m+n}{2}=k\).

(A) 1/4 (B) 1/3 (C) 4/3 (D) 3 (E) 4 We can solve it using integers..i would like to take negative integers first r.......t.......p.................s.......0 5....4......3................1 on solving (1+4)/(4+5) = 3 Just to check with positive integers 0.......r.......t.......p.................s 0.......2......3........4................6 on solving (63)/(32) = 3 Hence D

(A) 1/4 (B) 1/3 (C) 4/3 (D) 3 (E) 4 Find endpoints. Sketch r < s. From info and logic, neither p nor t can be an endpoint; both are midpoints. r < s, p is halfway between: R_____________P_____________S  t is halfway between p and r: R______T______P____________S xx2x Track on distance as above. Then use smallest length to define. Let RT = x. Then TP = x, and PS = 2x. Assign integer value to x; 1 is easy. Assign cardinal values in keeping with the ratios. Let r = 1. Then t = 2, p = 3, and s, which is 2x = (2)(1) away from p, = 5. A. (s  t) => (5  2) = 3 B. (t  r) => (2  1) = 1 \(\frac{A}{B}\) = \(\frac{3}{1}\) = 3 I tested it with x=2 as well, and started with r = 3. The ratio holds. Answer D

No ? thanks & have a great weekend

No ? thanks & have a great weekend Hey dave13 , Halfway means middle of the two numbers. So, If the distance between you and I is 1000 Kms, then the halfway between us will be 500 Kms away from both of us. Does that make sense?
