The length of pipe U is
23 of the length of pipe X and the length of pipe X is
13 of the length of pipe V and
110 of the length of pipe W. What fraction of the total length of the 4 pipes is pipe W?

The length of pipe X is repeated. Make the length of pipe X the same. LCM of 3 and 1 is 3.
Total length of all the 4 pipes
= 2 u + 3 u + 9 u + 30 u
= 44 u
