Finding What CancelsDate: 03/26/2003 at 19:44:55 From: Amanda Subject: Algebra Question: (1 1/2)(1 1/3)(1 1/4)(1 1/5).... Find how many factors it will take to reach the product of 1000. Date: 03/27/2003 at 00:37:42 From: Doctor Ian Subject: Re: Algebra Hi Amanda, It's easier to see if you write the mixed numbers as improper fractions, (1 1/2)(1 1/3)(1 1/4)(1 1/5).... = (3/2)(4/3)(5/4)(6/5)... 3 4 5 6 = - * - * - * - * ... 2 3 4 5 which makes it easier to see what cancels. Does this help? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
