Using Fractions to Read DecimalsDate: 08/29/2001 at 11:27:24 From: Julius Dorfman Subject: Reading decimals I am having trouble reading decimals. Can you please tell me how to read in words, decimals such as: .02 .20 .020 .002 .025 .0256 .02456 Thank you very much for your help, Julius Date: 08/29/2001 at 12:10:57 From: Doctor Peterson Subject: Re: Reading decimals Hi, Julius. Here's one way to keep track of the meaning of a decimal. Write the decimal, and below it put a 1 (under the one's place in the number) followed by a decimal point and a zero for every decimal place in the number: 0.02 ---- 1.00 Now take out both decimal points, and you have the fraction equivalent to the decimal: 002 --- 100 So 0.02 means "2 hundredths." Similarly, 0.02456 002456 ------- = ------ 1.00000 100000 so 0.02456 means "2,456 hundred-thousandths." You don't really have to write all this out; just count the decimal places in the number, and use that number of zeros to picture the denominator. What we're actually doing is writing a "fraction" using decimals that is equal to your decimal number (since a denominator of 1 doesn't change the number); then multiplying the numerator and denominator of this number by ten repeatedly until we have two whole numbers and can say the fraction. I hope this helps. Write back if you need any more help. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/ |
