Answer:
We need to convert both measurements to the same unit in order to compare them. Let's convert 6 1/3 feet to inches:
1 foot = 12 inches
6 feet = 6 x 12 = 72 inches
1/3 foot = (1/3) x 12 = 4 inches
6 1/3 feet = 72 + 4 + (1/3) x 12 = 76 inches
Therefore, the plumber has 76 inches of piping.
Since the plumber needs 75 inches of piping, we can see that she does have enough piping.
