Unusual fractions
Math brain teasers require computations to solve.
What is so unusual about these fractions ?
19/95 26/65 16/64
19/95 26/65 16/64

Posted by supermew30 on Dec 23, 2001 Thats not true with the second one. 65 divided by 26=2.5. There is no such fraction as 1/2.5 |

Posted by Trev on Feb 04, 2002 actually, what he is saying is that if you take out the 6's it would become 2/5, which is 1/2.5 |

Posted by Nishoo on Nov 16, 2004 Perhaps I should clarify ... 19/95 = 1/5 when 9 is removed (19x1/19x5), 26/65 = 2/5 when 6 is removed (13x2/13x5), and 16/64 = 1/4 when 6 is removed (16x1/16x4). Does That Help  |

Posted by craziigurl1105 on Aug 03, 2005 The way i got it was by dividing 19 by 95, and i got .2, which is 1/5, and i did the same for all of them! great teaser      |

Posted by MarcM1098 on Oct 20, 2006 The only other fraction of 2-digit numbers that can be easily reduced like this is 49/98, although it reduces to 4/8 which is not in the simplest form which is 1/2 |

Posted by javaguru on Feb 09, 2009 I expect to solve all the math teasers, but it was still quite satisfying that I got this one so quickly. Cool teaser! |
