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
Answer
Each one can be reduced to its simplest form merely by cancelling the number which is common to both its numerator and its denominator.Hide

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! |
