Introduction to Fractions
A fraction represents a part of a whole. It is written as numerator/denominator where:
- Numerator: the number of parts taken.
- Denominator: the total number of equal parts in the whole.
Key Concepts:
- Proper fraction: numerator < denominator (e.g. 3/4).
- Improper fraction: numerator ≥ denominator (e.g. 5/4).
- Equivalent fractions: different fractions representing the same value (e.g. 1/2 = 2/4 = 3/6).
- Decimal conversion: divide numerator by denominator.
- Percentage: (decimal value × 100)%.
This application provides tools to perform fraction arithmetic, simplify fractions, and visualize portions with a pie chart.
