Taiga0.5 is a rational number. This is because it can be expressed as a ratio. (1/2) It also terminates, or ends. Rational numbers can be expressed as a ratio/fraction and terminates, or ends. It is not an integer because integers include -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, and so on. 0.5 is a rational number.

Is a rational number a subset of the set of integers?
not necessarily... An integer is a rational number, but so is any real number between consecutive integers.
Are all integers rational 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.
What is a number written as quotient of two integers where the denominator is not zero?
A rational number
An integer that is not rational?
The are an infinite number of rational numbers that are not integers, because a rational number is a number that is written as a ratio of two integers. For examble, 1/2 (i.e. a half) is a non-integer rational number. This form is generally called a fraction.
Every rational number can be expressed as a ratio of integers?
Yes, A rational number is any number that can be expressed as a fraction whose numerator and denominator are both integers. (For example, 7/3 is a rational number, but pi/3 is not.) Thus, any terminating decimal number is a rational number. Recurring decimals and integers are also rational numbers as they can all be expressed as fractions.
