The length of copper pipe V is
23 of the length of copper pipe Y and the length of copper pipe Y is
13 of the length of copper pipe W and
14 of the length of copper pipe X. What fraction of the total length of the 4 copper pipes is copper pipe X?

The length of copper pipe Y is repeated. Make the length of copper pipe Y the same. LCM of 3 and 1 is 3.
Total length of all the 4 copper pipes
= 2 u + 3 u + 9 u + 12 u
= 26 u
Copper Pipe XTotal Length =
1226 =
