The length of pipe V is
45 of the length of pipe Y and the length of pipe Y is
23 of the length of pipe W and
29 of the length of pipe X. What fraction of the total length of the 4 pipes is pipe W?

The length of pipe Y is repeated. Make the length of pipe Y the same. LCM of 5 and 2 is 10.
Total length of all the 4 pipes
= 8 u + 10 u + 15 u + 45 u
= 78 u
