In rational numbers, the number with the smallest absolute value is ______.

The absolute value of a positive number is a positive number; the absolute value of a negative number is a positive number; the absolute value of 0 is 0,
The positive number is greater than 0, so the number with the smallest absolute value is 0.
Therefore, the answer is:0.

Is infinite decimal a rational number Is Infinite Decimal a Rational Number

Not necessarily. If it is a circular decimal, it is a rational number. If it is not a circular decimal, it is not a rational number.
