The length of pipe G is
45 of the length of pipe K and the length of pipe K is
13 of the length of pipe H and
13 of the length of pipe J. What fraction of the total length of the 4 pipes is pipe J?

The length of pipe K is repeated. Make the length of pipe K the same. LCM of 5 and 1 is 5.
Total length of all the 4 pipes
= 4 u + 5 u + 15 u + 15 u
= 39 u
