Final answer:
Kyle is correct; they can make 21 bows by dividing the total amount of ribbon, 12.6 meters, by the length of ribbon needed for one bow, which is 0.6 meters.
Step-by-step explanation:
The question involves dividing the total length of ribbon by the length needed for one bow to determine how many bows can be made. This is a simple division problem. Sean says that they can make 2 bows since he calculates 12.6 / 0.6 to be 2.1, which is incorrect. Kyle says they can make 21 bows since he calculates 12.6 / 0.6 to be exactly 21, which is correct. The correct mathematical operation to determine the number of bows they can make from 12.6 meters of ribbon, when each bow requires 0.6 meters, is to divide 12.6 by 0.6. The correct calculation is 12.6 / 0.6 = 21. Therefore, Kyle is right and they can indeed make 21 bows.
