Question 302835
<font face="Garamond" size="+2">


No, 0.37 is NOT an irrational number.  An irrational number is a number that is not rational.  A rational number is a number that can be expressed as the quotient (or ratio -- hence the name rational) of two integers.  37 is an integer and 100 is an integer and 0.37 is EXACTLY equal to *[tex \LARGE \frac{37}{100}], therefore 0.37 is rational.  ANY number that can be EXACTLY expressed as a decimal, no matter how many decimal places it has, is a rational number.  Just count the number of decimal places represented, take away the decimal point, and make the denominator a 1 followed by a number of zeros equal to the count of decimal places.  Any decimal that repeats is also a rational number.
