Help pls? Thank you :)

it's the last one

Step-by-step explanation:

just look up "reciprocal" lol

this is just a definition

A fraction that is the multiplicative inverse of the given fraction

Step-by-step explanation:

Let's prove the possible answers wrong:

A fraction with 1 as a denominator could be 5/1.  But a fraction could also have a 1 in the numerator, like 1/5. 5/1 and 1/5 are reciprocals

A fraction whose numerator and denominator have the same value. That means the only number possible is 1, when it is 1/1. But 5/1 can be a reciprocal as well

A fraction with the numerator as 1. Wrong, it can be 5/1 as well.

The last one is correct because is a reciprocal is when the numerator and the denominator is switched, or multiplicatively inverted.

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
