Summary
This module provides a comprehensive overview of fractions, aiming to demystify the topic and enhance understanding for GRE exam preparation.
- Fractions can be positive or negative, and there's an infinite number of fractions between any two integers.
- Key terms include numerator (top part of a fraction) and denominator (bottom part).
- Fractions can be viewed through arithmetic (division) or visualization (pieces of a pie), employing different sides of the brain.
- Equivalent fractions have the same numerical value despite different numerators and denominators; they can be simplified to lowest terms for ease of calculation.
- Improper fractions (numerator larger than denominator) and mixed numerals (part integer, part fraction) are interchangeable, but improper fractions are generally more efficient for calculations.
