Fractions represent a part of a whole and consist of a numerator and a denominator. Understanding how to manipulate and simplify fractions is essential for solving various mathematical problems.
Key Concepts
- 1A fraction is composed of a numerator (top number) and a denominator (bottom number).
- 2To add or subtract fractions, they must have a common denominator.
- 3Multiplying fractions involves multiplying the numerators and the denominators.
- 4Dividing fractions requires multiplying by the reciprocal of the divisor.
- 5Fractions can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD).
Simple Explanation
A fraction shows how many parts of a whole you have. The top number (numerator) tells you how many parts you have, and the bottom number (denominator) tells you how many equal parts the whole is divided into. To work with fractions, you often need to make sure they have the same denominator for adding or subtracting, and you can multiply or divide them easily by following specific rules.
