Question

The number of accidental deaths among females aged 15-19 years is separated by race. There were 1,333 deaths between African-American females and white females in the age group. Two-hundred and twenty-seven (227), or 17% of these deaths were African-Americans. This calculation of 17% is an example of:_______.

Answer 1

Answer: Proportion

Explanation:

A proportion is a statement that two ratios are equal and it is written as two equal fractions a/b = c/d.

So, the proportion is the equality between two or more ratios. If a/b corresponds to the ratio, then a/b = c/d is equivalent to a proportion. This content often falls into the form of a problem.  The ratio is the comparison of two quantities and is measured from the division of two values, then: a/b. In a proportion the cross-products are equal.

For example, the total number of deaths is 1,333 and 227 ofthem are African-Americans.

Then, 227/13333 = P/100

were P represents the proportion we need to find out and 100 represents 100% which is the total number of deaths.

So, (227 x 100) / 1333 = P

P = 17%
