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

The length of stainless steel pipe U is repeated. Make the length of stainless steel pipe U the same. LCM of 3 and 1 is 3.
Total length of all the 4 stainless steel pipes
= 2 u + 3 u + 15 u + 15 u
= 35 u
