alpha2cen Posted December 23, 2010 Posted December 23, 2010 (edited) 3 ball /2=? 3 cup of water /2 =? . This is simple question. Give this answer and think again. . That,s the best answer, is not? Edited December 23, 2010 by alpha2cen -2
timo Posted December 23, 2010 Posted December 23, 2010 You should try to write in complete sentences. Also, you should make your point clear rather than posting "a chicken crosses the road. think about it!". Expecting people to invest time into your thoughts and at the same time putting less than five minutes of effort into it yourself is just rude. 2

Its important but we don't know. So forum is important. Every one could answer like this. 3 ball/2 =1.5 ball 3 cup of water/2 = 1.5 cup of water But it has some fault. I'll give next post tomorrow.

The fault: you incorrectly increase the number of significant figures. Edited December 23, 2010 by CaptainPanic
alpha2cen Posted December 24, 2010 Author Posted December 24, 2010 The fault: you incorrectly increase the number of significant figures. How about this solution? 1) 3 ball/2=? transform to dimensionless form = 3a /2, a[ball/ball] calculation = 1.5 a transform to dimension form = 1 ball + 1 part of teared ball 2) 3 cup of water /2=? transform to dimensionless form =3b/2, b[cup of water/cup of water] calculation =1.5b transform to dimension form = 1.5 cup of water When it is divided., water can not be changed it's original property. The unit , cup is not a measured value(cm, sec, ...). So the number of significant figure is not no problem.
khaled Posted January 29, 2011 Posted January 29, 2011 This problem is not a normal mathematical division, it's an integer division: let's assume that A is number of divided Objects, and B is number of members 1. using Integer division: X = A div B Y = A mod B if X = 1 then objects divided success, else failure if Y > 0 then Y objects remain after division if Y = A then division failed 2. using recurrence definition: S = { 0, 0, 0, ... }, S represent what every member owns ------------- a. IF [ B < 1 ] OR [ A < 1 ] THEN STOP b. z = A mod cut, where cut is number of objects meant for every member c. A = A - z d. Sb = z e. B = B - 1 f. GOTO STEP a -------------
alpha2cen Posted January 30, 2011 Author Posted January 30, 2011 This concept is some different. The main point what I state is the difference between arithmetic calculation and real life calculation. Arithmetic calculation should be done by using nondimensional number. If not, the result gives us some confusion. So good problem solving procedure is like this. make equation--->transfer dimensionless form --------> calculation ------>transfer dimension form----->result

Gozonji Posted February 8, 2011 Posted February 8, 2011 The unit , cup is not a measured value(cm, sec, ...). So the number of significant figure is not no problem. False. 1 cup=250ml
Cap'n Refsmmat Posted February 8, 2011 Posted February 8, 2011 False. 1 cup=250ml In metric. Cups are around 240 mL in the US, but it varies a good bt.
Gozonji Posted February 10, 2011 Posted February 10, 2011 In metric. Yes, in metric. Is there any other rational system of measurement around?
alpha2cen Posted February 10, 2011 Author Posted February 10, 2011 False. 1 cup=250ml But 1 cup does not have exact value. For example other units 1m=100cm 1kg=1000g and measured value is like this. 1.005m 1.00006kg But we generally do not use 0.23cup.

Which makes it an "exact value". 2 cups=500ml 0.23 cups=57.5ml Edited February 10, 2011 by Gozonji
John Cuthber Posted February 10, 2011 Posted February 10, 2011 Yes, in metric. Is there any other rational system of measurement around? Foot pound second or http://en.wikipedia.org/wiki/Natural_units Anyway, I'd like to know what alpha2cen thinks this thread has added to human understanding.
