Fractions, decimals and percentages present great difficulty for many children – and even adults. It is essential that children sitting grammar school entrance exams can perform calculations using numbers in these forms, as well as understanding how to compare a fraction with a percentage or a decimal number.

Many children struggle to understand how to simplify fractions or identify equivalent fractions. They may also have difficulty in calculating fractions of quantities. Similarly, many children have trouble in calculating percentages or working with decimal numbers. The ability to compare fractions with percentages and decimal numbers and to convert one to another (e.g. understanding that 4/5 = 80% = 0.8) is an essential skill for entrance exam success. Our Entrance Exam Maths Masterclass B: Number aims to give your child a solid understanding of these tricky numbers.
