Yes, -1/2 is a rational number

A rational number is a number which can be expressed as the quotient of two integers, a quotient being the solution to a division sum. Therefore, 1/2, or one half, is a rational number, equal to 0.5. However, 1/3, or one third, is an irrational number, because if you had to write the number out as a decimal, the number would continue to recur. Therefore, all integers are rational numbers, but not all rational numbers are integers. EDIT: 1/3 is a rational number, whoever said it wasn't is a moron.

A rational number is one where a whole number is over another whole number. 3 and 2 are both whole numbers so 3/2 is a rational number.

It is a rational number. One way this can be proved is that it can be represented as a fraction: 7/2.

The given whole number of -2 is a rational number

Every irrational number is NOT a rational number. For example, sqrt(2) is irrational but not rational. A natural number is a counting number or a whole number, such as 1, 2, 3, etc. A rational number is one that can be expressed as a ratio of two whole numbers, which may be positive or negative. So, -2 is a rational number but not a counting number (it is an integer, though). Also, 2/3 is a rational number but not a whole, counting number or a natural number.

A rational number is one which can be expressed as a ratio of 2 integers. An irrational number is one that cannot be expressed in such a way.

It is rational. It is a whole number so it cannot be irrational.

2 is a rational number and it is also a prime number
