Decimal Numerator?Date: 04/08/2003 at 11:46:06 From: Dyan Subject: Math Is there such a thing as .8/1 ? I am not sure if a decimal can be a numerator or denominator. If I start with 80/100 and divide by 100, would an equivalent fraction be .8/1? Date: 04/08/2003 at 23:05:56 From: Doctor Peterson Subject: Re: Math Hi, Dyan. This is perfectly valid, except that ".8/1" is not a "common fraction," which always consists of whole numbers. So if you were asked to write the answer as a fraction, you would want to simplify it to 8/10, and then to 4/5. But if you are in the process of working out an answer to a problem, you can write ".8/1" with no trouble. The next step, most likely, would be to say that dividing by 1 doesn't change the number, so your value is simply .8. If you have any further questions, feel free to write back. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/ |
