Moving the Decimal PointDate: 12/04/2002 at 21:57:51 From: Tyler Woxland Subject: Division of Two decimals When you divide two decimals, what is it called when you move the decimal point? Date: 12/05/2002 at 11:28:49 From: Doctor Ian Subject: Re: Division of Two decimals Hi Tyler, Do you mean when you do something like this? ______ ________ 31.45 ) 216.5 ==> 3145 ) 21650.0 There's not really an official name for it, although it might fall under the category of 'equivalent fractions', since what you're really doing is this: 216.5 100 21650 ------- * ----- = ------- 31.45 100 3145 Does that make sense? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
