Joey can write #{3/4} / {1/16} = 12# cards.

Explanation:

The number of times a number #A# is repeated in other #B# equals dividing #B# by #A#:

#B/A = # number of times #A# is contained into #B#.

Then, if a card needs #1/16# of an hour to be written, in #3/4# of an hour there are:

#{3/4} / {1/16} = 12# periods of time to write a card, then you can write #12# cards.
