A rational number
Yes, a rational number is a real number. A rational number is a number that can be written as the quotient of two integers, a/b, where b does not equal 0. Integers are real numbers. The quotient of two real numbers is always a real number. The terms "rational" and "irrational" apply to the real numbers. There is no corresponding concept for any other types of numbers.
Yes. A rational number is a number that can be expressed as the quotient of two integers, the divisor not being zero. Since the divisor of an integer is 1, then all integers are rational.
All integers are rational numbers, but not all rational numbers are integers.2/1 = 2 is an integer1/2 is not an integerRational numbers are sometimesintegers.
a rational number is any number that can be expressed as the quotient or fraction a/b of two integers,yes
It is an incomplete definition of a rational number.
Probably because that's more or less the definition of "rational number": a number that can be expressed as a ratio of integers.
It is a rational number.
Yes it is. That is the definition of rational numebrs.
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).
a rational number
Yes. Rational numbers are always the quotient of two integers. Integers are always real, and you cannot divide a real number by another real number and get an imaginary number. So, true.
