# 8 3 As a Percent

Percentages are often used to illustrate the frequency of events, but in this context they might be misconstrued. Punctuation means that 8 3 ft is 200 and 12 3 ft is 240. Percentages don’t work right in this example.

### Add

. A real-world example could be: there are two girls in a group of five children. What's the percentage of girls? In other words, we want to know what's the ratio of girls to all children. It's 2 out of 5, or 2/5. We call the first number (2) a numerator and the second number (5) a denominator because this is a fraction. To calculate the percentage, multiply this fraction by 100 and add a percent sign.

You can also convert a mixed number to a percentage using fraction addition. First convert the whole number part of the mixed number to an improper fraction and add it to the fraction part of the mixed number. Then divide numerator by denominator and multiply by 100 to get the percent value. (Source: www.calculatorsoup.com)

### Divide

A mixed number is a whole number plus a fraction. You can convert fraction part of the mixed number to a decimal and then multiply by 100 to get the percent value. Alternatively you can convert mixed number to an improper fraction, and then convert it to a decimal by dividing numerator by denominator. Finally, multiply the decimal by 100 to find the percent value.

A fraction is defined as a portion of a whole quantity. A fraction simply represents the number of parts of a certain number divide a whole number. A simple fraction is composed of two parts namely the numerator, which is the number at the top, and the denominator being the number at the bottom. The slash line usually separates the numerator and the denominator. Examples of fractions include: 2/5, 1/3, 4/9 etc. (Source: www.storyofmathematics.com)
