Ok.

In the United States there are 254,212,610 privately owned and registered vehicles;

In the United States there are 223,877 privately owned and registered air craft

in the year 2009 there were 33,808 motor vehicle fatalities,

In the year 2009 there were 535 air craft fatalities.

What I am trying to figure out is this....

Based on the respective number of licensed vehicles, what is the annual death rate (for 2009) for accidents.

What is the percentage of people who are killed in each mode of transportation?


OMG I don't even know where to begin on this. I am really, hopeless when it comes to any sort of math stuff.

Your very kind and generous assistance is greatly appreciated. Thanks.

By my calculations, it's:


Auto deaths: 33,808/254,212,610 = 0.013%

Airplane deaths: 535/223,877 = 0.24%

Well, if every licensed vehicle (aircraft or automobile) has one registered owner, then to get the percentage you're looking for, use this equation:

(total number of fatalities / total number of registerd vehicles) * 100 - Do the math in the parenthesis first.

Example to get the percentage for registered aircraft:

(535 / 223877) = 0.0024 * 100 = .24% Percent (just less than 1/4 of a percent rounded off) .

The great thing about maths is that there's only one right answer... ^_^ I have Dyscalculia, so I can't help you with the answers, but if two people come up with the same answer, it's probably right.

.24 = 24%
.013 = 1.3%

The first person just forgot to multiply by 100 for the percentage.

Well, in many cases there is more than one right answer.

For example,
X^2 = 4 has more than one answer for X.

No, I didn't. It's .24%, not 24%. Not every percentage is a whole number.

'Dark of the Moon' is absolutely correct.

Nana053, remember learning percentages in 6th grade?
