For ANY number of the form , the multiplicative inverse is . In other words, to find the find the multiplicative inverse of any fraction, simply flip the fraction.

Note: if you multiply the number by the the multiplicative inverse you will get 1 since

So the multiplicative inverse of is

The multiplicative inverse of is

I'll let you do the rest of the problems involving a simple fraction
--------------------------

To find the multiplicative inverse of , we need to convert this mixed fraction into an improper fraction.

To do that, multiply the denominator 3 by the whole number 6 to get 18. Now add 18 to the numerator 1 to get 19. So

So the multiplicative inverse of is
