Question: Data from the Massachusetts Department of Health indicates that in 2003 there were 8,263 people in Massachusetts known to be HIV positive. The actual sample consisted of 123 people, but by expressing the case-fatality rate as a percent, we are saying that in a group of 100 people this frequency would be equivalent to 36 deaths. Percent means "per 100." It is a way of standardizing the results to make them easier to compare among different groups or at different times. The fraction of the sample that died was 44/123 = 0.36. The sample consisted of 123 people with documented bird flu. Visually we can represent this with the pie chart below. The decimal fraction 0.36 is equivalent to 36%. As a percentage: Once we have calculated the decimal fraction as we did above, the result can also be represented as a percentage (%). The decimal fraction (0.36) could also be represented as a percentage.This decimal fraction can be computed manually, in a spreadsheet, on a simple hand-held calculator, or by using the calculator on a smart phone. In this case, it would be reasonable to round this off to 0.36. As a simple fraction 44/123 people with confirmed H7N9 died.This proportion represents a case-fatality rate, and, like all proportions, it can be reported in several ways: They reported that 44 of these individuals died as a result of their infection. Q.5.The British Medical Journal reported on 123 confirmed cases of H7N9 avian flu (bird flu) admitted to hospitals.

Learn About Equivalent Fractions Here Frequently Asked Questions (FAQs) – Converting Percentage to Fraction, Decimal, Ratio This article, “Conversion of Percentage to Fraction, Decimals and Ratios,” help in understanding these in detail, and it helps solve the problems based on these very easily. The percentage symbol is removed in all circumstances, and the numeric value is divided by \(100.\) This article includes the definition of percent, fraction, decimals. The percentage’s numeric value can be a whole number, a fraction, or a decimal. It also depends on the percentage’s numerical value. The conversion of a percent to a fraction or other form of numbers is simple.
Mathematically a fraction is represented as \(\frac.\) A fraction is a part or section of a whole that can be any number, a particular value, or object. ”\)Ī percent is a number with no dimensions and no units of measurement.Įxamples: \(20\% ,\,64\% ,\,3.6\% ,\,…\) Fractionįractions can be defined as the parts of a whole and are represented as numerical values. The symbol used to represent the percent sign is \(“\%. A percentage is a relative value is indicating the hundredth parts of any quantity.
