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: \(\frac{m+n}{2}=k\).

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?
