1. Decimal Basics: Rounding, Ordering & Zeros
Learn the basics of working with decimals in math. Discover what decimals represent, how to round decimals up or down and how to order decimals. Explore these skills using several helpful examples.
2. Performing Operations with Decimals
Decimals are numbers with a whole portion and a fractional portion that are separated by a decimal point. Learn about performing operations with decimals and methods for adding, subtracting, multiplying, and dividing with decimals.
3. What is a Fraction? - Definition and Types
A fraction represents part of a whole expressed through a numerator and a denominator. Learn about the definition of fractions and explore different types of fractions such as proper and improper fractions, like and unlike fractions, and mixed numbers.
4. Changing Between Improper Fraction and Mixed Number Form
In mathematics, an improper fraction has a denominator that is smaller than its numerator, and a mixed number is composed of an integer paired with a proper fraction. Practice examples to learn how to change between the forms for improper fractions and mixed numbers. Understand when each form is appropriate and should be used over the alternate form.
5. How to Raise and Reduce Fractions
To raise a fraction, the same number is multiplied by the numerator and the denominator; to reduce a fraction, division by the same number is used. Learn how to raise and reduce fractions with examples.
6. Practice with Fraction and Mixed Number Arithmetic
In mathematics, arithmetic studies and manipulates numbers using addition, subtraction, multiplication, and division. Learn how to use these operations on fractions and mixed numbers, and gain additional understanding by doing practice problems that use the operation of mixed number arithmetic.
7. Converting Decimals to Fractions (and Back)
In mathematics, decimals and fractions both represent numbers that are not whole. Learn how to convert decimals to fractions, as well as how to convert fractions to decimals. Work problems to gain more understanding.
8. Using the Number Line to Compare Decimals, Fractions, and Whole Numbers
A number line is a line constructed with numbers that are plotted in order and at regular intervals. Learn how to use a number line to compare decimals, fractions, and whole numbers.
