How to Build and Reduce Fractions

1. How to Build and Reduce Fractions

In mathematics, fractions are numerical quantities used to represent something that is a portion of a whole, such as a piece of pie that is 1/8, or one of eight pieces, of an entire pie. Learn what fractions are and recognize the difference between the numerator and denominator. Explore how to build and then how to reduce fractions, and understand the role of the greatest common factor (GCF) in this process.

How to Find Least Common Denominators

2. How to Find Least Common Denominators

Finding the least common denominator requires calculating the least common multiple of two or more denominators. Learn the definition of multiples, explore how to use them to find the least common denominator, and understand the examples.

How to Add and Subtract Like Fractions and Mixed Numbers

3. How to Add and Subtract Like Fractions and Mixed Numbers

After determining a common denominator in a problem with mixed numbers and fractions, adding and subtracting fractions and mixed numbers requires two more steps. Learn how to add and subtract like fractions and mixed numbers, and review examples.

How to Add and Subtract Unlike Fractions and Mixed Numbers

4. How to Add and Subtract Unlike Fractions and Mixed Numbers

Some of the most commonly seen forms of fractions are unlike fractions and mixed numbers. Learn to add and subtract unlike fractions and mixed numbers by reviewing how fractions are handled then explore these processes using real-life examples.

Multiplying Fractions and Mixed Numbers

5. Multiplying Fractions and Mixed Numbers

Fractions can be multiplied, even when presented as mixed numbers, where an integer accompanies a fraction. Demonstrate understanding through solving examples in dollars, and practicing multiplying fractions and mixed numbers.

Dividing Fractions and Mixed Numbers

6. Dividing Fractions and Mixed Numbers

Fractions can be divided even when presented as mixed numbers, which is where an integer accompanies a fraction. Practice the division of fractions and mixed numbers in a series of practical scenarios.

Practice with Fraction and Mixed Number Arithmetic

7. 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.

Solving Problems using Fractions and Mixed Numbers

8. Solving Problems using Fractions and Mixed Numbers

From understanding a recipe to deciding the winner of a competition, fractions have many uses in solving everyday problems. Learn how to use fractions and mixed numbers, including comparisons, addition, subtraction, multiplication, and division to solve problems.
