6/8 is greater all you need to do is cross multiply take the 2 x8=16 16 goes over the 2/5 now cross multiply 6x5=30 30 over the 6 now what ever number is bigger over that fraction is greater hope this helps
Alliteration describes when there is a repetition of a letter or sound with connected words.
(EX: Pickled, Peter, Peppers...)
I believe it's unknown since the Mississippi is the predicate and unknown is a describing word, a.k.a. an adjective but I'm not sure
Good luck, hope I helped!
Personification (ex: the curtains danced)
I would say that “He runs fast despite his old age.”
