If 7 ft 9 inches is cut from a piece of wood that is 9 ft 6 inches, the piece left is
Answer: 1 foot 9 inches
Explanation
Step 1: Convert to Inches
Since 1 foot = 12 inches, we first convert both measurements to inches:
- 9 feet 6 inches = 9×12+6=108+6=114 inches
- 7 feet 9 inches = 7×12+9=84+9=93 inches
Step 2: Subtract
114 inches−93 inches=21 inches
Step 3: Convert Back to Feet and Inches
Since 21 inches is more than 1 foot (12 inches), we convert:
- 21 inches = 1 foot 9 inches (since 21−12=9)
