45 of the length of pipe N and the length of pipe N is
23 of the length of pipe L and
23 of the length of pipe M. What fraction of the total length of the 4 pipes is pipe L?

The length of pipe N is repeated. Make the length of pipe N the same. LCM of 5 and 2 is 10.
Total length of all the 4 pipes
= 8 u + 10 u + 15 u + 15 u
= 48 u
