Question

A pipefitter starts with 1/4 of an inch of pipe and increases it 1/3 of an inch with bushing. How wide is the new pipe opening?

Answer 1

The new width of the pipe opening, you add the original diameter of 1/4 inch to the increase of 1/3 inch, converting them to have a common denominator. The resulting width of the new pipe opening is 7/12 of an inch.

Step-by-step explanation:

To determine the new width of the pipe opening after increasing it by a bushing, we need to add the original diameter of the pipe to the increase provided by the bushing.


The pipe begins with a 1/4 inch diameter, and it is increased by 1/3 of an inch.

First, find a common denominator to add these two fractions. The smallest common denominator for 4 and 3 is 12.


Convert each fraction to have the denominator of 12:

• 1/4 inch becomes 3/12 inch
  
  
• 1/3 inch becomes 4/12 inch
  
  

Now that we have the same denominator, we can add the numerators:

3/12 inch + 4/12 inch = 7/12 inch

So the new width of the pipe opening is 7/12 of an inch.
