When the number is 0.
The answer depends on whether the "opposite" means the multiplicative inverse or the additive inverse.
The number 0.6666 is a rational number. Expressed as a fraction it is equal to 6666/10000.
Yes
Yes! When the number is negative, the absolute value of it'll be its opposite.
When the number is 0.
When the number is non-positive.
The answer depends on whether the "opposite" means the multiplicative inverse or the additive inverse.
Only if the rational number is 0.
No, never.
If a number is zero or positive, then its absolute value is equal to the number.
Absolute values are essentially used for the magnitude (distance) to zero of a number. They are represented by a number inside a vertical bar (e.g., |2|) E.g.'s: | 2 | = 2 (the absolute value of 2 is equal to 2) | -4 | = 4 (the absolute value of -4 is 4) In terms of rational numbers, it just means to hold the fraction. Rational numbers can be written in a/b (fraction) form. E.g.'s: | 1+2/3 | = 1+2/3 (the absolute value of one and two thirds is equal to one and two thirds) | -1-2/3| = 1+2/3 (the absolute value of -1 minus 2/3 is equal to 1 and 2/3.
The number 0.6666 is a rational number. Expressed as a fraction it is equal to 6666/10000.

Consider the absolute values (the numerical values ignoring the signs) of the two numbers. If these are equal then the sum is equal; otherwise the sum takes the sign of which ever number has the larger absolute value.
Yes, 100 is a rational number.A rational number is any number that can be expressed as the quotient a/b of two integers, with the denominator b not equal to zero. Since b may be equal to 1, every integer is a rational number.
