Key Mathematical Concepts

Least Common Denominator (LCD)
- Represents the least common multiple (LCM) of the denominators of multiple fractions, facilitating addition or subtraction of those fractions.
Percent
- Refers to a ratio that expresses how much out of 100, often used to illustrate proportions in a comprehensible manner.
Rational Number
- Encompasses all numbers that can be expressed as fractions, including integers and terminating or repeating decimals.
Decimal
- Describes numbers that feature digits to the right of a decimal point, used to represent fractions in a base-10 system.
Fraction
- Composed of a numerator (top part) and a denominator (bottom part), indicating a division of quantities.
Greatest Common Factor (GCF)
- The highest number that can evenly divide two or more numbers, useful for simplifying fractions.
Least Common Multiple (LCM)
- The smallest positive integer that is divisible by each number in a given set, important for finding common denominators.
