All rational numbers can be expressed as a fractions

all rational numbers can be written as fractions. That is the definition of rational numbers.

Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.

Yes, that is the definition of rational numbers.

Yes, 0.3 is a rational, for it can be written as a fraction. By definition, rational numbers are any numbers that can written as a fraction.

I don't know another single word for rational numbers. Definition: The rational numbers are all numbers which can be expressed as the ratio of two integers.

Yes. By definition, all rational numbers can be expressed as a ratio of two integers, the second of which is not zero. That is the fractional form of rational numbers.

-3.606 = -3606/1000 so by the definition of rational numbers, it's rational.

Rational numbers are numbers that can be written as a fraction. A whole number is a number with no decimals.

Yes, irrational numbers are never rational numbers because irrational numbers can't be expressed, by definition, as a fraction of two integers.

There are rational numbers and irrational numbers. Real numbers are DEFINED as the union of the set of all rational numbers and the set of all irrational numbers. Consequently, all rationals, by definition, must be real numbers.

The integers. Also: the rational numbers, the real numbers and (depending on your definition) the complex numbers.

A rational number is any number that can also be expressed as a fraction.

No, 300/2 = 150, which is a rational number.It's also the ratio of two whole numbers, and that'sexactly the definition of a rational number.

Real numbers are defined as the set of rational numbers together with irrational numbers. So rationals are a subset of reals, by definition.

Yes, by definition. A rational number is one that can be written as a ratio (hence rational) of two whole numbers. And a ratio of two whole numbers is a fraction.

Yes, that is their definition!

No, because all fractions are rational numbers

a fraction is the representation of a number as the quotient of two integers. all rational numbers can be written as a fraction, and all fractions represent rational numbers.

The quotient of two nonzero integers is the definition of a rational number. There are nonzero numbers other than integers (imaginary, rational non-integers) that the quotient of would not be a rational number. If the two nonzero numbers are rational themselves, then the quotient will be rational. (For example, 4 divided by 2 is 2: all of those numbers are rational).

Integers are a subset of the set of all rational numbers. By definition, a rational number can be exactly expressed as the ratio of two integers. Only if the ratio can be simplified so that the denominator is 1 is a rational number an integer.

There is no such number. The empty set is a subset of rational numbers and, by definition, it contains no numbers so nothing that can be common to any other subset.Alternatively, all rational numbers less than -1 and all rational numbers greater than 1 are subsets of rational numbers. There is no number common to them.

A real number that can not be expressed as a rational number.

Zero is a rational number, and therefore is NOT an irrational number. The definition of a rational number is any number that can be expressed as a fraction where the numerator and demoninator are both integers, and the denominator is non-zero. Irrational numbers are all real numbers that are not rational numbers. Since zero qualifies under the definition of a rational number, (0/3, for example), it therefore cannot be an irrational number.
