Final answer:
No material needs to be removed from the pipe because the original length (2/8 inch) is equivalent to the desired length (1/4 inch) after simplification.
Step-by-step explanation:
The question involves finding the difference in length between two measurements of a pipe. To find out how much of the pipe needs to be removed to shorten a 2/8 inch pipe to a 1/4 inch, we need to subtract the desired length from the original length.
First, we note that 2/8 inches simplifies to 1/4 inches since they are equivalent. So, we have:
Original length: 2/8 inch (which is the same as 1/4 inch)
Desired length: 1/4 inch
When we subtract the desired length from the original length, we get:
2/8 inch - 1/4 inch = 1/4 inch - 1/4 inch = 0 inches
Therefore, no material needs to be removed from the pipe since the original and desired lengths are equivalent.
