Understanding Fractions

Fractions are a fundamental concept in GCSE Maths, representing parts of a whole. They consist of a numerator and a denominator. The numerator indicates how many parts are being considered, while the denominator shows the total number of equal parts.

Types of Fractions

• Proper Fractions: The numerator is less than the denominator (e.g., 3/4).
• Improper Fractions: The numerator is greater than or equal to the denominator (e.g., 5/3).
• Mixed Numbers: A whole number combined with a fraction (e.g., 2 1/2).

Operations with Fractions

Performing operations with fractions involves addition, subtraction, multiplication, and division. Here are the basic rules:

• Addition/Subtraction: Convert to a common denominator before performing the operation.
• Multiplication: Multiply the numerators and denominators directly.
• Division: Multiply by the reciprocal of the divisor.

This image illustrates a circle divided into four equal parts, with one part shaded to represent the fraction 1/4.

Exploring Proportions

Proportions are equations that express two ratios as equal. They are used to solve problems involving scaling and resizing.

Solving Proportions

To solve proportions, use cross-multiplication. This involves multiplying the numerator of one ratio by the denominator of the other and setting the products equal.

Applications of Proportions

Proportions are widely used in real-life scenarios, such as:

• Cooking: Adjusting recipes based on serving sizes.
• Maps: Understanding scale to determine actual distances.
• Art: Resizing images while maintaining aspect ratios.
