Fractions, Decimals, and Percents
This document defines decimals, fractions, and percents and provides steps for converting between them. Decimals are numbers with a decimal point, fractions show parts of a whole, and percents express amounts out of 100. To convert a fraction to a decimal, divide the numerator by the denominator. To convert a fraction to a percent, change it to a decimal then multiply by 100. Converting between other forms follows similar steps of changing the number to an equivalent decimal or percent value.
Decimals And Percents
This document provides instructions for converting percentages to decimals in two steps:
1) Remove the % sign
2) Move the decimal point two places to the left
Performing these two steps has the same effect as multiplying the percentage by 100 and dividing by 100, which cancels out to equal the original number expressed as a decimal. Several examples are provided, such as 97% = 0.97 and 1/2% = 0.005.

Converting fractions, decimals, and percents
This document provides instructions for converting between decimals, percentages, and fractions. It explains that to convert a decimal to a percent, move the decimal point two places to the right and add a percent sign. To convert a percent to a decimal, move the decimal point two places to the left. To convert a fraction to a decimal, divide the numerator by the denominator. And to convert a percent to a fraction, first change it to a decimal and then write the decimal over 100. Examples are given for each type of conversion.
Mulitply Whole Numbers and Decimals
To multiply decimals, you multiply the numbers as whole numbers and then count decimal places to determine where to place the decimal point in the answer. For the multiplication 1.3 x 3, you multiply 3 x 3 = 9 and 3 x 1 = 3, writing 39 without regard to decimals. Since there is one decimal place in the original numbers, the decimal point goes after the first digit in the answer, making 3.9.

It also discusses simplifying expressions with exponents by applying exponent rules such as the power of a product property.
Fraction Talking Power Point 1
This document explains how to change improper fractions to mixed fractions. An improper fraction has a numerator larger than or equal to the denominator, while a mixed fraction is a whole number and proper fraction combined. To change an improper fraction to a mixed fraction, divide the numerator by the denominator. The number of times the denominator divides into the numerator becomes the whole number part, and the remainder is the numerator of the fractional part over the original denominator. Examples are provided to demonstrate this process.

Fractions & decimals
This document provides instructions for converting decimals to fractions and fractions to decimals. It explains that for decimals to fractions, the whole number is the numerator, the place value of the decimal determines the denominator, and the number to the right of the decimal is the numerator. For fractions to decimals, the fraction is set up as a division problem, with the numerator as the dividend and denominator as the divisor, zeros are added as placeholders, and the decimal is pulled up into the quotient. Examples are provided and the document emphasizes keeping track of place value in the conversions.
Fractions
Fractions can be represented as a numerical quantity that is not a whole number, broken into portions. Examples include 1/2, 2/3, 25/37, and 79/100. Fractions can represent things in daily life and can be added or subtracted by finding the lowest common denominator and applying the same operation to the numerators. Improper fractions have a numerator larger than the denominator and can be simplified by dividing both the numerator and denominator by their common factor.

q are integers, and
�
q is not zero. This means that rational numbers include both positive and negative fractions, as well as whole numbers and zero. Essentially, if a number can be written in the form of a fraction, it is considered rational. This encompasses a broad range of numbers such as
1
2
2
1
, -3, 0.75, and 5, highlighting the flexibility and wide applicability of rational numbers in various mathematical contexts. The term "rational" itself is derived from the word "ratio," reflecting the idea that these numbers represent ratios of integers. Rational numbers are a subset of real numbers, and they can be precisely located on the number line. An important characteristic of rational numbers is that when expressed in decimal form, they either terminate or repeat. For example, the decimal representation of
1
4
4
1
is 0.25, which terminates, while
1
3
3
1
is 0.333..., which repeats. This property differentiates rational numbers from irrational numbers, which cannot be expressed as exact fractions and have non-terminating, non-repeating decimal expansions. Rational numbers play a crucial role in various areas of mathematics and everyday life. In algebra, they are used to solve equations and inequalities, and in geometry, they help in measuring lengths, areas, and volumes. In everyday life, rational numbers are used in financial calculations, such as determining interest rates, discounts, and budgeting, as well as in measurements and recipes. Understanding rational numbers is essential for mathematical literacy and is a foundational concept for more advanced topics in mathematics, such as calculus and number theory. Moreover, rational numbers are integral to computer science, particularly in algorithms and programming, where precise calculations and representations of numbers are necessary. The ability to manipulate and understand rational numbers enhances problem-solving skills and logical reasoning. The study of rational numbers also involves exploring their properties, such as the ability to perform arithmetic operations like addition, subtraction, multiplication, and division, which follow specific rules and patterns. This exploration extends to understanding how rational numbers relate to other types of numbers, such as integers and irrational numbers, and how they fit within the broader number system. Overall, rational numbers are a versatile and essential component of mathematics, with applications that extend far beyond the classroom, influencing various fields and everyday situations. Their study provides a strong foundation for mathematical understanding and practical problem-solving abilities.
Rational numbers are also significant in the study of number theory and real analysis, where they provide insight into the properties and behaviors of numbers
Rational numbers
Rational numbers can be represented as fractions p/q where p and q are integers and q is not equal to 0. Rational numbers are closed under addition, subtraction, and multiplication, meaning these operations on rational numbers will always result in another rational number. Division of rational numbers is not closed as division by 0 is undefined. Rational numbers exhibit properties like commutativity for addition and multiplication but not for subtraction or division. They also demonstrate the associative and distributive properties. Every rational number has an additive inverse and a multiplicative inverse or reciprocal. Zero is the additive identity and one is the multiplicative identity.
Fractions
The document describes how to perform fraction operations including: dividing fractions by inverting the second fraction and multiplying the numerators and denominators; dividing fractions by whole numbers by treating the whole number as a fraction over 1; and provides examples of dividing fractions.
Introduction To Simplifying Fractions
1) The document discusses equivalent fractions and how fractions can represent the same quantity even if written differently.
2) It provides examples of how 1/2 is equivalent to 2/4 because both represent one of two equal parts of a whole.
3) The key to finding equivalent fractions is to divide both the numerator and denominator by a common factor to simplify the fraction into equivalent lower terms.
