To determine the height of the post, we add the length of the post (6 3/4 feet) and the depth it is installed below ground level (1 1/2 feet).
First, convert the mixed numbers to improper fractions:
6 3/4 = 27/4
1 1/2 = 3/2
Next, add the fractions:
27/4 + 3/2
To add the fractions, the denominators must be the same. Since 4 is a factor of 2, we can convert 2 to have a denominator of 4:
27/4 + 3/2 = 27/4 + (3/2)*(2/2) = 27/4 + 6/4 = 33/4
The height of the post is 33/4 feet.
Regarding the expression "27/8 5l/9", it appears to be incorrect or incomplete. The fraction "5l/9" is not a valid mathematical expression.
