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

The length of pipe X is repeated. Make the length of pipe X the same. LCM of 2 and 1 is 2.
Total length of all the 4 pipes
= 1 u + 2 u + 6 u + 6 u
= 15 u
