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

The length of pipe P is repeated. Make the length of pipe P 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
