Half a cup of flour, a third off the price, a quarter tank of petrol, splitting a bill three ways — fractions are how we talk about parts of a whole every single day. In the O/L paper they turn up on their own and hidden inside almost every other topic: ratios, percentages, algebra, mensuration. Get fractions fluent now and a large slice of the paper becomes easy marks; stay shaky and small slips will follow you everywhere. This lesson makes them second nature.
