45 of the length of pipe H and the length of pipe H is
13 of the length of pipe F and
16 of the length of pipe G. What fraction of the total length of the 4 pipes is pipe F?

The length of pipe H is repeated. Make the length of pipe H the same. LCM of 5 and 1 is 5.
Total length of all the 4 pipes
= 4 u + 5 u + 15 u + 30 u
= 54 u
