Answer: the plant is 6 1/4 inches above the ground.
Explanation:
In her garden Pam plants the seed 5 and one fourth inches below the ground. Converting 5 and one fourth inches to improper fraction, it becomes 21/4 inches.
After one month the tomato plant has grown a total of 11 and one half inches. Converting 11 and one half inches to improper fraction, it becomes 23/2 inches.
The height of the the plant above the ground would be
23/2 - 21/4 = (46 - 21)/4 = 25/4
Converting to mixed fraction, it becomes
6 1/4 inches
