Decimals and Percentages

This page focuses on the relationship between decimals, fractions, and percentages. It provides a comprehensive list of conversions that are essential for students to memorize when working with fractions, decimals, and percentages.

The page starts with decimal-to-fraction-to-percentage conversions, presenting them in a clear, easy-to-read format. For instance, it shows that 0.1 equals 1/10 and 10%, 0.2 equals 2/10 (or 1/5) and 20%, and so on up to 0.9 equaling 9/10 and 90%.

The latter part of the page introduces a new section specifically on decimals, emphasizing important decimal-to-fraction conversions. This section reinforces the relationship between fractions and decimals, which is crucial for students to understand when working with these mathematical concepts.

Definition: Decimals are a way of writing fractions as part of the base-10 number system, using a decimal point to separate whole numbers from fractional parts.

Example: 0.5 = 5/10 or 1/2 and 50%

Highlight: The page stresses the importance of remembering these conversions, as they form the basis for more complex mathematical operations involving fractions, decimals, and percentages.

Fractions and Decimals

This final page continues the focus on the relationship between fractions and decimals, providing a detailed list of conversions that students should memorize. These conversions are crucial for solving problems involving fractions, decimals, and percentages in various mathematical contexts.

The page presents a comprehensive list of fraction-to-decimal conversions, starting from 1/10 equaling 0.1 and progressing through tenths up to 10/10 equaling 1. This systematic presentation helps students recognize the pattern in these conversions, making it easier to remember and apply them.

Key conversions highlighted on this page include 1/2 (or 5/10) equaling 0.5, which is a fundamental conversion that students often use in various calculations. The page also reinforces the conversions for other common fractions like 3/10, 7/10, and 9/10 to their respective decimal forms.

Example: 1/2 (5/10) = 0.5

Highlight: The inclusion of 10/10 = 1 at the end of the list emphasizes the concept of a whole in decimal form, which is important for students to understand when working with fractions and decimals.

Vocabulary: Fractions - A way of expressing a part of a whole, represented by a numerator (top number) and a denominator (bottom number).

This page, along with the previous two, forms a comprehensive guide for students learning to convert between fractions, decimals, and percentages. Mastering these conversions is essential for success in more advanced mathematical topics and real-world applications.
