The number 0.5 is rational because

It is the square root of a perfect square
It is a decimal that dose not repeat or terminate
It is a decimal that repeats
It is the square root of a non-perfect square
It I'd a decimal that terminated

The number 0.5 is rational because it is a decimal that terminates.

The number 0.5 is rational because it is a decimal that terminates.

The number 0.5 is rational because it is a decimal that terminates.

To determine if a number is rational, we need to examine its decimal representation. A rational number is one that can be expressed as a fraction, where the numerator and denominator are both integers.

In the case of 0.5, its decimal representation terminates after the first digit (0.5). This means that there are a finite number of digits after the decimal point.

To confirm that 0.5 terminates, we can express it as a fraction:

0.5 = 1/2

Since both the numerator (1) and the denominator (2) are integers, we can conclude that 0.5 is a rational number.
