These facts and definitions should be mastered throughout this unit. This page can be used for periodic review and study as you are finishing the unit and in the future.
Facts and Definitions
Lesson 1: Basic Fraction Review
- Numerator: the top number in a fraction, how many parts of the whole you have or need
- Denominator: the bottom number in a fraction, the total number of equal parts in a whole
Lesson 2: Equivalent Fractions
- Equivalent fractions: fractions that are the same size but have different numerators and denominators
- To create an equivalent fraction, you multiply or divide both the numerator and denominator by the same number.
Lesson 3: Comparing Fractions
- [none]
Lesson 4: Going Further With Comparing Fractions
- If you want to compare two fractions with different denominators, you can find a multiple that both denominators share, create equivalent fractions using the shared denominators, and then compare those fractions.
Lesson 5: Building Fractions
- Unit fraction: a fraction that has a numerator of 1
- Mixed number: a number that is a combination of a whole number and a fraction (1 1/2, 2 3/4, etc.)
Lesson 6: Adding Fractions
- [none]
Lesson 7: Subtracting Fractions
- [none]
Lesson 8: Simplifying Fractions
- Simplifying (or reducing) a fraction means to find an equivalent fraction with the smallest possible numerator and denominator
Lesson 9: Solving Fraction Problems
- [none]
Lesson 10: Adding Mixed Numbers
- Improper fraction: a fraction that has a greater number in the numerator than in the denominator
- When adding mixed numbers, add the whole numbers first and then add the fractions
- In a proper fraction, the number in the numerator is less than the number in the denominator
Lesson 11: Subtracting Mixed Numbers
- When subtracting mixed numbers, stack them vertically, subtract the fractions portion, and then subtract the number portion. If the top fraction is smaller than the bottom fraction, borrowing and regrouping must take place.
Lesson 12: Multiplying Fractions and Whole Numbers
- When multiplying a fraction by a whole number, multiply the numerator by the whole number and leave the denominator the same.
