Neo is making samples of one of her fashion designs. She has 14 yards of fabric. Each sample takes 2 ¼ yards of fabric. How many samples can she make?
Divide! The clue is you are taking a total amount (14 yards) and seeing how many 2 1/4 yards pieces Neo can cut from the 14 yards. Don't forget to KCF! The exact answer would be 6 2/9, but since you can't make 2/9 of a clothing sample, we would drop our remainder and final answer is 6. (Give yourself points if you got 6 2/9 just know that could be tricky with multiple choice!)

Divide! You are starting with the total amount of 24 ft of rope, and you are seeing how many 3 1/5 feet pieces the Boy Scouts can cut from that. Don't forget 24 has to come first, and you have to KCF! Exact Answer: 7 1/2, but since no one wants to rock climb with 1/2 of a rope, we will drop our remainder and say 7. Give yourself points if you said 7 1/2, just know that might be tricky in multiple choice!
