If the decimal number can be expressed as a fraction (with one whole number over another), then it is a rational decimal number. So 7/5 is a rational number, and remains as such even if expressed in decimal form (of 1.4).

A line over the decimal part of a number indicates that there is a part that recurs infinitely many times. Such numbers are rational.

A rational number has the form of one integer over another; this can be converted to decimal form by dividing the top number (numerator) by the bottom number (denominator). Example: 2/5 = 2 ÷ 5 = 0.4

A rational number is any number that can be written in the form of one integer over another integer; all rational numbers have a decimal form that either terminates or repeats one, or more, digits forever. 4.680 is a terminating decimal, therefore it is a rational number. 4.680 = 4680/1000 = 468/100 = 117/25 -------------------------- The decimal form of a rational number will repeat forever if the prime factorization of the denominator contains any prime other than 2 or 5.

A decimal is a rational number if:* It terminates - i.e., it has a finite number of decimal digits. * It doesn't terminate, but it repeats the same pattern over and over - possibly after a finite number of digits that are not included in the pattern. For example, 0.145145145145..., or 3.125252525...

All rational numbers are those than can be expressed as one whole number over another. 3.87655 = 387655/100000 = 77531/2000 which is of this form, so it is a rational number. The decimal representation of a rational number either terminated or ends with a repeating sequence of digits.

We know that a real number is rational if and only if, when expressed as a decimal, it has a finite or recurring expansion. . . (put a point exactly over 8 and 2). For example, 5/4 = 1.25, 2/3 = 0.6, 20/7 = 2.857142857 or 20/7 = 2.857142

-42 is rational. All integers are rational numbers as they can be expressed as the number over 1 which, being one integer over another integer, is the form of a rational number.

A "rational number" is one that can be written as a fraction, with integers in the numerator and the denominator. When written as a decimal number, you'll get either a terminating decimal (e.g., 8 / 5 = 1.6), or a periodic decimal - one that repeats eventually, over and over again (e.g., 1 / 7 = 0.142857 142857 142857 ...).
