Fractions represent a part of a whole and are expressed as a ratio of two integers, where the top number is the numerator and the bottom number is the denominator. Understanding how to manipulate fractions is essential for solving a variety of mathematical problems in the Edexcel curriculum.
Key Concepts
- 1A fraction consists of a numerator and a denominator.
- 2To add or subtract fractions, they must have a common denominator.
- 3Multiplying fractions involves multiplying the numerators and denominators directly.
- 4To divide fractions, multiply 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 part is called the numerator, and the bottom part is the denominator. To add or subtract fractions, you need to make sure they have the same denominator. You can multiply fractions by multiplying the top numbers together and the bottom numbers together.
Memory Trick
“Remember 'Top times top, bottom times bottom' for multiplying fractions, and 'Flip and multiply' for dividing fractions.”
