Step 1: Convert to Inches

Since 1 foot = 12 inches, we first convert both measurements to inches:

• 9 feet 6 inches = $9 times 12 + 6 = 108 + 6 = 114$ inches
• 7 feet 9 inches = $7\times 12+9=84+9=93$ inches

Step 2: Subtract

$$114\text{ inches}-93\text{ inches}=21\text{ inches}$$

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 $21 - 12 = 9$)
