45 of the length of rod R and the length of rod R is
13 of the length of rod P and
12 of the length of rod Q. What fraction of the total length of the 4 rods is rod Q?

The length of rod R is repeated. Make the length of rod R the same. LCM of 5 and 1 is 5.
Total length of all the 4 rods
= 4 u + 5 u + 15 u + 10 u
= 34 u
