A plumber adds 6.25" of pipe to an existing line that is 10.5' long. Expressed as a fraction, the length of the extended pipe, not including the fitting, is now:

a. \( \frac{21.75}{2} \)

b. \( \frac{21.25}{2} \)

c. \( \frac{85}{8} \)

d. \( \frac{85}{4} \)

Answer :

Final answer:

When a plumber adds 6.25" of pipe to a line 10.5' long, the total length, not including the fitting, is 132.25 inches or 85/4 as a fraction. so the correct option is d. 85/4

Explanation:

In this scenario, we have a plumber adding 6.25" of pipe to a line that is 10.5' long. To find the total length in inches, we need to convert the feet to inches first: 10.5 feet x 12 inches/foot = 126 inches. Adding the extra 6.25 inches gives a total of 132.25 inches. The fraction for the extended pipe length is 85/4(choice d).
