The length of metallic rod V is
45 of the length of metallic rod Y and the length of metallic rod Y is
15 of the length of metallic rod W and
14 of the length of metallic rod X. What fraction of the total length of the 4 metallic rods is metallic rod X?

The length of metallic rod Y is repeated. Make the length of metallic rod Y the same. LCM of 5 and 1 is 5.
Total length of all the 4 metallic rods
= 4 u + 5 u + 25 u + 20 u
= 54 u
