N2.1 Understand equivalent fractions, simplifying a fraction by cancelling all common factors.
Candidates should be able to:
identify equivalent fractions
simplify a fraction by cancelling all common factors using a calculator where appropriate. For example, simplifying fractions that represent probabilities.
Notes
This is part of the core number work required across all units. This will generally be tested within statistics questions.
Examples
From inspection of a histogram (histogram would be provided) – What fraction of the times were under one hour? Give your answer in its simplest form.
From inspection of a box plot (box plot would be provided) – What fraction of the birds were under 20g? (20g being the lower quartile) Give your answer in its simplest form.
Trading standards inspect 80 bags of apples to check they are 1 kg as stated. (Stem-and-leaf diagram would be provided.) The stem-and-leaf diagram shows the weight of the bags under 1 kg. What fraction of bags were under 1 kg? Give your answer in its simplest form.
