What is the sum of the lengths 6'6", 5'9", and 2'1 1/2"?

Explanation:
To calculate the sum of the lengths 6'6", 5'9", and 2'1 1/2", first convert each measurement into inches for ease of addition: 1. **6'6"** is converted as follows: - 6 feet = 6 x 12 = 72 inches - Add the 6 inches: 72 + 6 = 78 inches 2. **5'9"** is converted as follows: - 5 feet = 5 x 12 = 60 inches - Add the 9 inches: 60 + 9 = 69 inches 3. **2'1 1/2"** is converted as follows: - 2 feet = 2 x 12 = 24 inches - 1/2 inch is 0.5 inches: 24 + 1 + 0.5 = 25.5 inches Now, add these three values together: - 78 inches + 69 inches + 25.5 inches = 172.5 inches Next, convert the total inches back into feet and inches: - 172.5 inches divided by 12 equals 14

To calculate the sum of the lengths 6'6", 5'9", and 2'1 1/2", first convert each measurement into inches for ease of addition:

  1. 6'6" is converted as follows:

  • 6 feet = 6 x 12 = 72 inches

  • Add the 6 inches: 72 + 6 = 78 inches

  1. 5'9" is converted as follows:

  • 5 feet = 5 x 12 = 60 inches

  • Add the 9 inches: 60 + 9 = 69 inches

  1. 2'1 1/2" is converted as follows:

  • 2 feet = 2 x 12 = 24 inches

  • 1/2 inch is 0.5 inches: 24 + 1 + 0.5 = 25.5 inches

Now, add these three values together:

  • 78 inches + 69 inches + 25.5 inches = 172.5 inches

Next, convert the total inches back into feet and inches:

  • 172.5 inches divided by 12 equals 14
