The length of stainless steel pipe R is
12 of the length of stainless steel pipe U and the length of stainless steel pipe U is
12 of the length of stainless steel pipe S and
17 of the length of stainless steel pipe T. What fraction of the total length of the 4 stainless steel pipes is stainless steel pipe T?

The length of stainless steel pipe U is repeated. Make the length of stainless steel pipe U the same. LCM of 2 and 1 is 2.
Total length of all the 4 stainless steel pipes
= 1 u + 2 u + 4 u + 14 u
= 21 u
