To find the height of the post, we need to subtract the portion of the post that is installed below ground level from its total length.
The total length of the post is 4 1/4 feet. To convert this mixed fraction to an improper fraction, we multiply the whole number (4) by the denominator (4), then add the numerator (1). This gives us 17/4 feet.
The portion of the post below ground level is 7/8 feet.
To find the height, we subtract the portion below ground level from the total length:
17/4 - 7/8 = (17/4) * (2/2) - 7/8
= 34/8 - 7/8
= (34 - 7) / 8
= 27/8 feet.
Therefore, the height of the post is 27/8 feet or 3 3/8 feet.
