Problem 185

Textbook Question

Write each fraction as a percent. 2/11

Verified step by step guidance

Start by understanding that to convert a fraction to a percent, you need to multiply the fraction by 100.

Write the fraction \( \frac{2}{11} \) and set up the multiplication: \( \frac{2}{11} \times 100 \).

Perform the multiplication: Multiply the numerator (2) by 100 to get 200.

Divide the result from the multiplication (200) by the denominator (11) to find the percentage.

Express the result as a percentage by adding the percent symbol (%) to the quotient.

Fractions

A fraction represents a part of a whole and is expressed as a ratio of two integers, where the numerator indicates how many parts are taken and the denominator indicates the total number of equal parts. Understanding fractions is essential for converting them into other forms, such as decimals or percentages.

Percentages

A percentage is a way of expressing a number as a fraction of 100. It is often used to compare proportions and is calculated by multiplying the fraction by 100. For example, to convert a fraction to a percentage, you can multiply the fraction by 100 and add the percent sign.

Conversion Techniques

Conversion techniques involve methods used to change one form of representation to another, such as converting fractions to percentages. This typically includes multiplying the fraction by 100 and simplifying the result, which is crucial for accurately interpreting and comparing different numerical values.
