Is 7 over 5 as a fraction a rational or irrational number as a decimal?
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).

Is 3.87655is a rational number?
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.
Is 7 over 5 as a fraction a rational or irrational number as a decimal?

Can a rational number be a decimal?
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
Is 4.680 a rational number?
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.
How is a decimal a rational number?
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...
Is 3.87655is a rational number?
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.
Is it rational or irrational if there is a line over the decimal?
A line over the decimal part of a number indicates that there is a part that recurs infinitely many times. Such numbers are rational.
When a number is written in decimal form how can you tell if it's a rational number?
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
How are decimal that are rational number described?
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 ...).
Is -42 rational or irrational?
-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.
