last night I calculated 2040x7.65 in my head in like 45 seconds and IIRC I calculated 15,906 but it's 15,606 and now I'm sad.

the two correct answers:

there are two ways of doing answering question, I know the top heavy way (the one on the right) but the 3 13/15 answer has confused me, can anyone explain how you would get to that?

Very simple mathematical formula that you can find everywhere in some form, though there are many different forms of the Fibonacci sequence with their own formulas.

have you seen the equation for the nth fibonacci number
its not very simple

It's basically turning an improper fraction into a mixed number.

58/15 is equal to 3 (13/15), where 3 can be written as 45/15. When you add 13/15 to 45/15, you get 58/15, which is 3 (13/15), likewise.

i hate math it's my weakest subject and my lowest subscore on the ACT. 36 english, 26 math, 36 reading, 33 science.

like i can do math if i have time. unfortunately the ACT is more of a test of "how fast can you do this" rather than "can you do this at all" so.
