How much is 3 inches in hundredths of a foot?

• A. 0.25
• B. 0.50
• C. 0.75
• D. 0.35

Answer: (D)

Think about feet first. There are 12 inches in a foot, so to turn inches into feet you divide by 12. For 3 inches, that’s 3/12, which equals 0.25 feet. If you’re expressing the measurement in hundredths of a foot, multiply by 100: 0.25 × 100 = 25, so 3 inches is 25 hundredths of a foot. In other words, 3 inches corresponds to 0.25 feet (or 25 hundredths of a foot). The values given in the choices map to different lengths: 0.50 feet is 6 inches, 0.75 feet is 9 inches, and 0.35 feet is 4.2 inches. The correct representation for 3 inches is 0.25 feet.
