katana078 Posted May 24, 2005 Share Posted May 24, 2005 .246=.2 .236=.2 .226=.2 .216=.2 .206=.2 1 limits the number to a max of .246 and a minimum of .206, both of which rounds to .2. 2 limits the number to the list above, all rounded to .2 both individually are sufficient to answer the question.

rd_eastbay Posted May 24, 2005 Share Posted May 24, 2005 Since we are rounding to the tenth's digit, .246 doesn't round to .25 but directly to .2 (as .246 Quote Link to comment Share on other sites More sharing options...
katana078 Posted May 24, 2005 Share Posted May 24, 2005 same mistake I made when I did it quickly. don't round from 3 decimal place to 2nd then to the tenth digit. 0.2499999999999 rounds to 0.2 Quote Link to comment Share on other sites More sharing options...
