The length of metallic rod R is
34 of the length of metallic rod U and the length of metallic rod U is
13 of the length of metallic rod S and
12 of the length of metallic rod T. What fraction of the total length of the 4 metallic rods is metallic rod S?

The length of metallic rod U is repeated. Make the length of metallic rod U the same. LCM of 4 and 1 is 4.
Total length of all the 4 metallic rods
= 3 u + 4 u + 12 u + 8 u
= 27 u
