Problem 181

Textbook Question

Write each fraction as a percent. 4/5

Verified step by step guidance

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

Take the fraction \( \frac{4}{5} \) and set up the multiplication: \( \frac{4}{5} \times 100 \).

Multiply the numerator (4) by 100 to get 400.

Divide the result (400) by the denominator (5) to simplify the expression.

The result of this division will give you the percentage equivalent of the fraction \( \frac{4}{5} \).

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

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 denoted by the symbol '%'. To convert a fraction to a percentage, you multiply the fraction by 100 and add the percent sign, which helps in understanding relative sizes and comparisons.

Conversion Techniques

Conversion techniques involve methods used to change a number from one form to another, such as from a fraction to a percentage. This typically includes multiplying the fraction by 100 and simplifying the result. Mastery of these techniques is crucial for solving problems that require different numerical representations.
