anonymous · Answer

I just typed it in my calculator.. so.. idk.. lol

anonymous · Answer

okay so if you divide 78/274 it would give u a totally different sum from 6/19 so.. yah

anonymous · Answer

So which one would be right and why?

anonymous · Answer

the ratio is just the fraction for endangered over the total... so 78/274.
if you reduced that you can divide both by 2 and get 39/137
which is reduced.
