#+2 1/4 and -4/9#

Explanation:

The term "opposite" probably refers the the value which is the distance from 0 on the numberline, but on the opposite side.
The opposite of #-2 1/4 is +2 1/4#

This is also known as the 'additive inverse'

Additive inverses have the property that their sum is 0.

#-2 1/4 + 2 1/4 = 0#

The 'reciprocal' of a number is the number 'turned upside down'.

It is also known as the multiplicative inverse.

Reciprocals have the property that their product is equal to 1.

#-2 1/4 = -9/4# Its reciprocal is #-4/9#

#-9/4 xx -4/9 = 1#
