posts;6 3/4 feet in length post must be installed 1 1/2 feet below ground level what is the height
27/8 5l/9 Which one is taller
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.
To find the height of the post, you need to subtract the length the post must be installed below the ground level from the overall length of the post.
Length of post: 6 3/4 feet
Length below ground level: 1 1/2 feet
To convert the mixed numbers to improper fractions:
6 3/4 = (4 x 6 + 3)/4 = 27/4
1 1/2 = (2 x 1 + 1)/2 = 3/2
Now, subtract the length below ground level from the overall length of the post:
27/4 - 3/2
To subtract fractions, you need to have a common denominator. The common denominator of 4 and 2 is 4.
Now, convert 3/2 to have a denominator of 4:
3/2 = (2 x 3)/ (2 x 2) = 6/4
Subtracting the fractions:
27/4 - 6/4 = (27 - 6)/4 = 21/4
The height of the post is 21/4 feet.
Regarding the comparison between 27/8 and 5l/9, 5l/9 is not a valid fraction. Please provide the correct fraction so that a comparison can be made.
