8.5 + 2.75 = 11.25 feet
8.5 feet above ground plus 2.75 feet below ground is 11.25 feet of post.
5,000,000,000,000,000,000,000,000,000,000,000,000,000
To do this, you may add the 8 + 2 to get 10 feet and then add the fractions.
To add the fractions, you must covert them to a common denominator which would be 4 in this case. Therefore,
2/4 + 3/4 = 5/4 = 1 1/4
Then add the 1 1/4 to the 10 and you have 11 1/4.
