Re: [math-fun] Kindergarten example of almost-integer mystery

Wait! Isn't 6/5 - 529/441 = 1/2205 exactly? --ms On 2/5/2011 10:45 AM, Dan Asimov wrote:

A crossword puzzle with a 23x23 grid is 529/441 times as large as one with a 21x21 grid.

529/441 is almost 1.2, and the difference D satisfies

1/D = 2204.999999999853571+.

Its difference from an integer satisfies

|2205 - 1/D|< 1.5 e-10
