How to add Feet and Inches

• Add the inches together.
• If the number of inches is greater than 12, divide the inches by 12.
• The quotient is the number of feet that need to be added to the other feet.
• The remainder is the number of extra inches.
• Add the original feet plus the whole feet resulting from the addition of the inches.

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

• Add 8 inches to 10 inches:
  8 + 10 = 18 inches
• The number of inches is greater than 12 so divide by 12:
  18 ÷ 12 = 1 foot 6 inches
• Add the Feet:
  5 + 3 + 1 = 9 feet
• Answer: 9 feet 6 inches
