Adding Feet and Inches

Add Feet and Inches: Learn

Since there are 12 inches in a foot, this is how to add feet and inches:

  • Add the inches together.
  • Add the feet together.
  • If the number of inches is 12 or more, regroup the inches into feet:
    • Divide the inches by 12.
    • Add the quotient to the number of feet.
    • The remainder is the number of extra inches.

Example: Add 5 feet 8 inches plus 3 feet 10 inches:

  • 8 + 10 = 18 inches
  • 5 + 3 = 8 feet
  • Since 18 is 12 or more, regroup the inches into feet:
    18 ÷ 12 = 1 foot 6 inches
  • Final answer: 9 feet 6 inches
