The length of copper pipe U is
45 of the length of copper pipe X and the length of copper pipe X is
15 of the length of copper pipe V and
12 of the length of copper pipe W. What fraction of the total length of the 4 copper pipes is copper pipe W?

The length of copper pipe X is repeated. Make the length of copper pipe X the same. LCM of 5 and 1 is 5.
Total length of all the 4 copper pipes
= 4 u + 5 u + 25 u + 10 u
= 44 u
