Study Notes
Vocabulary Related to Fractions and Area
- Mixed Number: A combination of a whole number and a fraction, representing values greater than one whole.
- Reciprocals: A pair of numbers whose multiplication results in one; e.g., the reciprocal of 4 is 1/4.
- Fraction: A numerical representation indicating a part of a whole, expressed as a numerator over a denominator.
- Numerator: Represents the number of parts being considered in a fraction, located above the fraction line.
- Denominator: The divisor in a fraction, indicating how many equal parts the whole is divided into, located below the fraction line.
Mathematical Concepts and Operations
- Order of Operations: Follows the acronym PEMDAS to determine the sequence of operations in calculations: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.
- Product: The result obtained from multiplying two or more numbers together.
Factors and Multiples
- Greatest Common Factor (GCF): The largest factor that is common to two or more numbers, used to simplify fractions and solve problems involving divisibility.
- Least Common Multiple (LCM): The smallest multiple shared by two or more numbers, useful for finding common denominators in fraction addition or subtraction.
Measurements Related to Area
- Area: The total square units needed to cover a surface, calculated using the formula: Area = Length x Width.
- Length: The measurement of distance between two points, used as one of the dimensions in area calculation.
- Width: The side-to-side measurement of an object, also used in calculating area alongside length.
