so from accidental deaths we have
30 from falls
47 from fires
200 from drowning
1950 car accidents
so the total of those is 30+47+200+1950, or 2227.
the ones that weren't car accidents will be 2227 - 1950, or 277.
if we take 2227 to be the 100%, how much is 277 off of it in percentage?
[tex] \bf \begin{array}{ccll}amount&\%\\\cline{1-2}2227&100\\277&x\end{array}\implies \cfrac{2227}{277}=\cfrac{100}{x}\implies x=\cfrac{277\cdot 100}{2227}\\\\\\x\approx 12.4382577~\hspace{7em}\stackrel{rounded~up}{x=12} [/tex]
