The product of a number and its reciprocal is always what?
The product of a number and its reciprocal is always one. That's what reciprocal means.
What is the reciprocal of 2 and 1 over 3?
Oh, dude, the reciprocal of a number is just 1 divided by that number. So, the reciprocal of 2 is 1/2, and the reciprocal of 1/3 is 3. So, the reciprocal of 2 and 1/3 is 1/(2 + 1/3) which simplifies to 3/7. Easy peasy, like basic math stuff, you know?
What is the reciprocal of .68?

Why is the reciprocal of the opposite of a nonzero number the opposite of the reciprocal of the number?
Taking the reciprocal (multiplicative inverse) does not affect the positive or negative status of an integer. So the reciprocal of a negative number is negative and the reciprocal of a positive number is positive. The reciprocals will be opposites (positive/negative) just as the original numbers were.
