The multiplicative inverse of a number is the reciprocal of the number.
For a whole number this would be making it a fraction with 1 as the numerator.
The  multiplicative inverse of 5 is 1/5
Multiplicative inverse means that the numerator and denominator switch places. Remember that all non fraction numbers can be turned into a fraction by making the denominator 1 like so...
[tex]\frac{5}{1}[/tex]
Now you can take the multiplicative inverse of 5/1 to get...
[tex]\frac{1}{5}[/tex]
^^^That is equal to 0.2
Hope this helped!
