Final answer:
To convert four and a half yards to inches, you multiply 4.5 by 3 to get feet and then by 12 to get inches, resulting in a total of 162 inches.
Step-by-step explanation:
The question involves converting measurements from yards to inches. When Carlos and his grandmother require additional fabric for their rug, they need to know the equivalent of four and a half yards in inches.
Since there are 3 feet in a yard and 12 inches in a foot, we use the conversion factor to calculate the total number of inches.
Multiply the number of yards (4.5) by the number of feet in a yard (3) and then by the number of inches in a foot (12) to obtain the answer.
1. Convert yards to feet: 4.5 yards × 3 feet/yard = 13.5 feet
2. Convert feet to inches: 13.5 feet × 12 inches/foot = 162 inches.
Therefore, four and a half yards of fabric is equal to 162 inches.
