Featured Fraction Vocabulary Words On These Puzzles

Addition – Addition is a mathematical operation that combines two or more numbers to find their total or sum. In the context of fractions, addition involves finding the total sum of two or more fractions or mixed numbers.

Common Denominator – A common denominator is the least common multiple of the denominators of two or more fractions, necessary for adding or subtracting fractions. For example, to add 1/3 and 1/4, a common denominator of 12 is required.

Composite Number – A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In contrast to prime numbers, composite numbers are divisible by factors other than 1 and themselves.

Denominator – In a fraction, the denominator represents the total number of equal parts into which a whole is divided, appearing as the bottom number of the fraction. For instance, in the fraction 3/5, 5 is the denominator, indicating the whole is divided into 5 equal parts.

Equivalent Fractions – Equivalent fractions are fractions that represent the same part of a whole or the same point on the number line, even though they may look different. They have equal values but may be expressed in different forms. For example, 1/2, 2/4, and 3/6 are all equivalent fractions.

Fraction – A fraction is a numerical representation of a part of a whole or a ratio of two quantities, consisting of a numerator and a denominator separated by a horizontal line. Fractions are used to express values that are less than one whole, such as 1/2 or 3/4 .

Greatest Common Divisor (GCD) – The greatest common divisor (GCD) of two or more integers is the largest positive integer that divides each of the integers without leaving a remainder. It is crucial for simplifying fractions to their lowest terms by dividing both the numerator and the denominator by their GCD.

Improper Fraction – An improper fraction is a fraction in which the numerator is greater than or equal to the denominator, representing a value that is greater than one whole. Improper fractions can be converted into mixed numbers or expressed in other forms for better representation.

Integer – An integer is a whole number that can be positive, negative, or zero, without any fractional or decimal parts. Integers include all natural numbers, their negatives, and zero, and they are used in arithmetic operations including fractions.

Least Common Denominator (LCD) – The least common denominator (LCD) of two or more fractions is the smallest common multiple of their denominators, necessary for adding and subtracting fractions with different denominators. It is found by identifying the least common multiple of the denominators.

Least Common Multiple (LCM) – The least common multiple (LCM) of two or more integers is the smallest positive integer that is divisible by each of the numbers. It is important for finding the least common denominator of fractions.

Mixed Number – A mixed number is a combination of a whole number and a proper fraction, representing a quantity that is greater than one whole. Mixed numbers can be converted into improper fractions or expressed in other forms.

Multiple – A multiple of a number is the product of that number and an integer. For instance, multiples of 3 include 3, 6, 9, 12, and so on, indicating numbers that are divisible by 3 without leaving a remainder.

Numerator – In a fraction, the numerator represents the number of equal parts being considered, appearing as the top number of the fraction. For instance, in the fraction 3/5, 3 is the numerator, indicating 3 out of 5 equal parts.

Prime Factorization – Prime factorization is the process of expressing a composite number as a product of prime numbers. It is crucial for finding the greatest common divisor and simplifying fractions to their lowest terms.

Prime Number – A prime number is a positive integer greater than 1 that has exactly two distinct positive divisors – 1 and itself. Examples of prime numbers include 2, 3, 5, 7, 11, and so on, as they cannot be divided evenly by any other numbers.

Product – The product is the result obtained when two or more numbers are multiplied together. In the context of fractions, it refers to the result obtained when multiplying two fractions together.

Proper Fraction – A proper fraction is a fraction in which the numerator is less than the denominator, representing a value that is less than one whole. Proper fractions are commonly used to represent parts of a whole or ratios.

Quotient – In division, the quotient is the result obtained by dividing one number (the dividend) by another number (the divisor). In fractions, the quotient represents the result of dividing one fraction by another.

Reciprocal – The reciprocal of a fraction is another fraction obtained by interchanging the numerator and the denominator. When multiplied together, a fraction and its reciprocal result in a product of 1.

Simplify – To simplify a fraction means to reduce it to its simplest form by dividing both the numerator and the denominator by their greatest common divisor. It results in a fraction with the smallest possible numerator and denominator.

Subtraction – Subtraction is a mathematical operation that finds the difference between two quantities or numbers. In the context of fractions, subtraction involves finding the difference between two fractions or mixed numbers.

Sum – Sum is the result obtained when two or more numbers are added together. In the context of fractions, it refers to the result obtained when adding two or more fractions together.

Whole Number – A whole number is a non-negative integer, including zero, that does not have any fractional or decimal parts. Whole numbers are used in arithmetic operations and can be considered as fractions with a denominator of 1.

Zero – Zero is the integer that represents the absence of quantity or value. In fractions, zero can serve as the numerator or the denominator, resulting in fractions with a value of zero.
