Fractions can be smaller, equal to, or larger than whole numbers, depending on their numerator and denominator.
Misconception: Fractions are only used when dealing with parts of a whole.
- While fractions are commonly used to represent parts of a whole, they can also represent ratios, proportions, and division. Fractions can be used to compare quantities, express probabilities, and solve various mathematical problems that involve division or ratios.
Clarifying the difference between terminating and recurring decimals
Misconception: Terminating decimals are always rational numbers.
- Terminating decimals are decimal numbers that have a finite number of digits after the decimal point. While many terminating decimals are indeed rational numbers (numbers that can be expressed as a fraction), not all terminating decimals are rational. For example, the decimal 0.333… (recurring threes) is a repeating decimal and is rational because it can be expressed as 1/3. However, the decimal 0.123456789101112… (continuing indefinitely) is a non-repeating decimal and is irrational.
Misconception: Recurring decimals are always irrational numbers.
- Recurring decimals are decimal numbers that have a repeating pattern of digits after the decimal point. While many recurring decimals are indeed irrational numbers (numbers that cannot be expressed as a fraction), not all recurring decimals are irrational. For example, the decimal 0.666… (recurring sixes) is a repeating decimal and is rational because it can be expressed as 2/3. However, the decimal 0.101001000100001… (continuing indefinitely) is a non-repeating decimal and is irrational.
