The length of copper pipe M is
34 of the length of copper pipe Q and the length of copper pipe Q is
23 of the length of copper pipe N and
27 of the length of copper pipe P. What fraction of the total length of the 4 copper pipes is copper pipe N?

The length of copper pipe Q is repeated. Make the length of copper pipe Q the same. LCM of 4 and 2 is 4.
Total length of all the 4 copper pipes
= 3 u + 4 u + 6 u + 14 u
= 27 u
