Changing a Repeating Decimal to a FractionDate: 09/22/2002 at 00:00:15 From: Nicole Subject: Fractions and decimals How do you change 0.75 in bar notation to a fraction? Date: 09/22/2002 at 01:35:02 From: Doctor Ian Subject: Re: Fractions and decimals Hi Nicole, Do you mean __ 0.757575... = 0.75 = ? If so, consider this: x = 0.757575... 100x = 75.757575... 100x - x = 75 99x = 75 x = 75/99 Does that make sense? Do you see how you could do something similar for other repeating fractions? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
