45 of the length of pipe H and the length of pipe H is
23 of the length of pipe F and
23 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 2 is 10.
Total length of all the 4 pipes
= 8 u + 10 u + 15 u + 15 u
= 48 u
