Answer:
C
Step-by-step explanation:
The multiplicative inverse of a number n is [tex]\frac{1}{n}[/tex]
Given
5 [tex]\frac{4}{5}[/tex] ← convert to an improper fraction
= [tex]\frac{5(5)+4}{5}[/tex] = [tex]\frac{25+4}{5}[/tex] = [tex]\frac{29}{5}[/tex]
Thus the multiplicative inverse is
[tex]\frac{1}{\frac{29}{5} }[/tex] = [tex]\frac{5}{29}[/tex] → C
