Question

ella is 66 inches tall. andy is $6\frac{1}{2}$ feet tall. who is taller? by how much? (12 inches = 1 foot)

Explanation:

Step1: Convert Andy's height to inches

Andy's height is $6\frac{1}{2}$ feet. First, convert the mixed number to an improper fraction: $6\frac{1}{2}=\frac{13}{2}$ feet. Since 1 foot = 12 inches, multiply by 12: $\frac{13}{2}\times12 = 13\times6 = 78$ inches.

Step2: Compare heights and find the difference

Ella's height is 66 inches. Andy's height is 78 inches. Since 78 > 66, Andy is taller. The difference is $78 - 66 = 12$ inches.

Answer:

Andy is taller. He is taller by 12 inches.
