The length of copper pipe R is
45 of the length of copper pipe U and the length of copper pipe U is
23 of the length of copper pipe S and
29 of the length of copper pipe T. What fraction of the total length of the 4 copper pipes is copper pipe T?

The length of copper pipe U is repeated. Make the length of copper pipe U the same. LCM of 5 and 2 is 10.
Total length of all the 4 copper pipes
= 8 u + 10 u + 15 u + 45 u
= 78 u
