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? Think carefully first, then make a decision:
He cuts off 50 / 5 = 10 feet. So he has 50 - 10 = 40 feet left. He gives half away which means he has 40 / 2 = 20 feet. So he has 20 / 2 = 10 sections. So, the answer is 10.
