23 of the length of pipe S and the length of pipe S is
14 of the length of pipe Q and
13 of the length of pipe R. What fraction of the total length of the 4 pipes is pipe Q?

The length of pipe S is repeated. Make the length of pipe S the same. LCM of 3 and 1 is 3.
Total length of all the 4 pipes
= 2 u + 3 u + 12 u + 9 u
= 26 u
