Karen can make 20 scarves.

Explanation:

If Karen has 5 yards of material and needs #1/4# yard for each scarf, we can divide 5 by #1/4# to get the number of scarves:
#5 div 1/4 #

Since we're dividing by a fraction, we multiply by the reciprocal:
#5 times 4/1 = 20#.

Thus, we know Karen can make 20 scarves.
