Study Notes
Definitions and Concepts
- A fraction represents a part of a whole.
- It's written as a/b, where 'a' is the numerator and 'b' is the denominator.
- The denominator indicates the total number of equal parts the whole is divided into.
- The numerator indicates how many of those equal parts are being considered.
- Fractions can represent quantities less than, equal to, or greater than one.
Types of Fractions
- Proper fraction: The numerator is smaller than the denominator (e.g., 2/3).
- Improper fraction: The numerator is greater than or equal to the denominator (e.g., 5/3).
- Mixed number: A combination of a whole number and a proper fraction (e.g., 1 2/3).
Equivalent Fractions
- Equivalent fractions represent the same value but have different numerators and denominators.
- They can be obtained by multiplying or dividing both the numerator and denominator by the same non-zero number.
- Simplification of fractions involves reducing the fraction to its simplest form by dividing both numerator and denominator by their greatest common divisor (GCD).
Comparing Fractions
- Comparing fractions with the same denominator is straightforward; the larger numerator corresponds to the larger fraction.
- Comparing fractions with different denominators requires finding a common denominator before comparison.
Adding and Subtracting Fractions
- Adding or subtracting fractions with the same denominator involves adding or subtracting the numerators and keeping the denominator the same.
- Adding or subtracting fractions with different denominators requires finding a common denominator.
Multiplying Fractions
- To multiply fractions, multiply the numerators and multiply the denominators.
- Simplify the resulting fraction, if possible.
Dividing Fractions
- To divide fractions, invert (reciprocate) the second fraction and then multiply the fractions.
- Simplify the resulting fraction, if possible.
Decimal Conversions
- Fractions can be converted to decimals by dividing the numerator by the denominator.
- Some fractions convert precisely to decimals, others as repeating decimals.
Real-World Applications
- Fractions are used in everyday situations like measuring ingredients, dividing objects, expressing parts of a whole, and more importantly, showing relative values and ratios.
- Examples include sharing a pizza, measuring ingredients in a recipe, and calculating discounts or percentages.
