The length of copper pipe H is
45 of the length of copper pipe L and the length of copper pipe L is
15 of the length of copper pipe J and
14 of the length of copper pipe K. What fraction of the total length of the 4 copper pipes is copper pipe K?

The length of copper pipe L is repeated. Make the length of copper pipe L the same. LCM of 5 and 1 is 5.
Total length of all the 4 copper pipes
= 4 u + 5 u + 25 u + 20 u
= 54 u
