When the number is 0.
The answer depends on whether the "opposite" means the multiplicative inverse or the additive inverse.

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.

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.
