#82# noodles with some dough left over to roll out and cut again.

Explanation:

The process will be to divide #2 3/4# feet by #2/5# of an inch.

#rarr# change feet into inches. #2 3/4# feet = #24+9 = 33# inches

(#2 3/4 xx 12 = 11/4 xx 12 = 11xx3 =33# inches)

#rarr# how many strips of #2/5# inch can be cut from #33# inches?

#rarr33 div2/5 = 33xx5/2 = 82.5# strips

She can make #82# strips and have some dough left over to roll out again.
