You just need to use the given information to retrieve all the lengths:

A is given B is 3/5 of A. Multiply the length of A by 3/5 and you'll get B C is 4/5 of B. Multiply the length of B by 4/5 and you'll get C D is 9/10 of C. Mulply the length of C by 9/10 and you'll get D E is the same as C, which we already got F is the same of B, which we already got.
