GCSE Maths Made Easy: Simplifying Fractions and Ratios for Exam Success
Mastering fractions and ratios is essential for success in GCSE Maths. These concepts form the foundation for many mathematical problems and are frequently tested in exams. This guide will help you simplify fractions and ratios with ease.
Understanding Fractions
Fractions represent a part of a whole and are composed of a numerator and a denominator. Simplifying fractions involves reducing them to their simplest form, where the numerator and denominator have no common factors other than 1.
- Identify the greatest common divisor (GCD) of the numerator and denominator.
- Divide both the numerator and the denominator by the GCD.
- For example, to simplify 8/12, the GCD is 4. Divide both by 4 to get 2/3.
Working with Ratios
Ratios compare two or more quantities and are expressed in the form a:b. Simplifying ratios is similar to simplifying fractions.
- Find the GCD of the numbers in the ratio.
- Divide each number in the ratio by the GCD.
- For example, to simplify the ratio 10:15, the GCD is 5. Divide both by 5 to get 2:3.
Practice Makes Perfect
Consistent practice is key to mastering these skills. Work through past exam papers and practice questions to build confidence and improve your ability to simplify fractions and ratios quickly and accurately.
