Fraction Vocabulary

Numerator The number or expression written above the line in a fraction. It shows the number of pieces out of the whole.
Denominator The quantity below the fraction bar. It tells the total number of equal parts into which the whole is divided.
Unit Fraction A fraction with a numerator of one. For example, 1/3, 1/5, 1/24, etc.
Benchmark Fraction Fractions that are commonly used in estimation. For example, 1/4, 3/4, 1/2, etc.
Equivalent Fraction Fractions that have the same value. For example, 4/8 = 1/2.
Improper Fraction A fraction where the numerator is greater than the denominator. For example, 6/5, 7/3, etc.
Proper Fraction A fraction less than one whole. The numerator is less than the denominator. For example, 3/8, 2/7, etc.
Simplify To express a fraction in simplest form. For example, 3/12 = 1/4.
Unlike Denominators Denominators that are NOT equal. For example, 3/5 and 5/7.
Lowest Terms A fraction where the numerator and denominator have no common factor greater than 1. For example, 1/2, 1/3, 3/5, 5/7.
Mixed Number A number written as a whole number and a fraction. Also called a mixed fraction. For example, 1 2/3.
