Answer:

#-9# is the opposite
#1/9# is the reciprocal

Explanation:

The opposite of a positive number is to add a negative sign. (Note: if the number is negative, you will change it to a positive number).

#"the opposite of 9 is -9"#

The reciprocal is simply flipping the denominator and numerator of a fraction. #9# is the same as saying:

#9/1# because any number divided by #1# is itself.

So we will flip:

#9/1 =>1/9# is the reciprocal.
