The length of stainless steel pipe T is
45 of the length of stainless steel pipe W and the length of stainless steel pipe W is
12 of the length of stainless steel pipe U and
15 of the length of stainless steel pipe V. What fraction of the total length of the 4 stainless steel pipes is stainless steel pipe U?

The length of stainless steel pipe W is repeated. Make the length of stainless steel pipe W the same. LCM of 5 and 1 is 5.
Total length of all the 4 stainless steel pipes
= 4 u + 5 u + 10 u + 25 u
= 44 u
