Not always because any number that can be expressed as a fraction is a rational number as for example 0.666...recurring can be expressed as 2/3 as a fraction

Why repeating decimals happen?
A repeating decimal is any rational number whose decimal representation does not terminate after a given number of digits. As only a very small quantity of the rational numbers terminate in their decimal representation, practically any rational number picked at random will be a repeating decimal.
Is 17.1 rational?
Yes. Any number that can be expressed as a finite or repeating decimal is a rational number. Irrational numbers have decimal expansions that neither repeat nor terminate.
Is 0.10100100010000 a rational number?
Since it has a terminating decimal (or binary or to any other rational base) representation, it must be rational.
Is 5.232323232323232323 a rational number?
To be a rational number, it must be able to be expressed as a fraction(i.e., p/q) where q is any number except zero (it can be 1). Your number can be expressed as 5232323232323232323/1000000000000000000 So it is rational.
What number produces a rational number when added to 15?
Any other rational number.

Is 11.9 rational or irrational?
In mathematics, a rational number is any number that can be expressed as the quotient (or fraction) a/b of two integers, with the denominator b not equal to zero.A rational number expressed as a decimal will always terminate (e.g. 11.9) or will continuously repeat the same finite sequence of digits (e.g. 10/9 = 1.1111111111111).11.9 can be expressed as the fraction 119/10, and therefore, is rational.

What number produces a rational number when added to 0.42?
Any other rational number.
What number produces a rational number when added to 15?
Any other rational number.
Is 1.86 a rational number?
Yes. Any number which can be written down to all its places exactly is rational. A proviso is that the base (most commonly base 2 or base 10) must also be rational. Any number which is the ratio of two rational numbers (such as 1/3, or 186/100) is rational.
Is 435.2 repeating rational?
Any decimal number that either terminates or ends in a repeating set of digits is a rational number. 435.222... = 435 2/9 = 3917/9 Any decimal that does not repeat and does not terminate is an irrational number, eg √2 = 1.414... and π = 3.14159... are both irrational numbers.
Why does any real number must be either a rational number or an irrational number?
It is due to the fact that the set of real numbers is defined as the union of the rational and irrational numbers.
Is 34 over 8 rational?
Yes. Any rational number divided by any other rational number is a rational number.
What type of number is the sum of any whole number and any rational number?
It is a rational number.
