How many times as heavy is the Golden Eagle of 13 9/10 llb as the Red-Tailed Hawk of 3 1/2?

Question

I never know if I have to divide or multiply. How can I tell with this problem?

I have 139/10 / 7/2 then 139/10 x 2/7 = 278/70 if I divide that it will give me 3.9714 how do I get my fraction back. 3 971/1000 is that the answer?

It is like this one as well?
How many times as heavy is the Golden Eagle of 13 9/10 as the Northern Bald Eagle of 9 9/10?

I have 139/10 / 99/10, with cross reduce it equals, 139/99 if I divide those it gives me 1.4040.

Am I any where near the correct answer?
