Decimals

Bayani Gaba-gaba

Decimals are the language of measurement. Every time you read a digital scale, compare prices or record a scientific result, you rely on decimal notation to express values that fall between whole numbers. Mastery of decimals feeds directly into percentages, standard form and calculator work across both Edexcel papers.

You will learn to read, write and order decimals, convert fluently between decimals, fractions and percentages, and understand why every terminating decimal can be written as a fraction. Higher tier students will also discover how to tame recurring decimals using algebra.

A stopwatch reading of 10.83 seconds, a petrol price of 1.479 per litre, the thickness of a coin measured as 0.175 cm: decimal notation lets us pin down quantities more precisely than whole numbers ever could. The digits to the right of the decimal point represent tenths, hundredths, thousandths, and so on.
