Bob buys 50 feet of rope.  He uses a 5th of it to make a small piece of art.  He takes the rest and gives half of it to the friend.  After that, he cuts 2-foot sections.  How many sections does he get?
He cuts off 50/5=<<50/5=10>>10 feet
So he has 50-10=<<50-10=40>>40 feet left
He gives half away which means he has 40/2=<<40/2=20>>20 feet
So he has 20/2=<<20/2=10>>10 sections
