Mike Lamb · Answer 1

To answer this question I would use ratios. I would set this up as 236 deaths/22.3 million people = x number of deaths / 309 million people. You could use cross products to solve for x. 309 x 236 = 22.3x. 72924 = 22.3x. Divide both sides by 22.3 to solve for X, or the number of deaths in the US. X = 3270 deaths. Another way to figure this out would be to figure out how many groups of 22.3 million Australian people there are in 309 million Americans. This factor would then be multiplied by 236 to get the number of deaths in the United States. The answer would be the same.
