Percentages
Bayani Gaba-gaba
Percentages are the language money speaks. A discount in a sale, the interest on a loan, a test score, a pay rise, the VAT on a receipt: all of them are percentages, and being quick with them is one of the most useful everyday skills mathematics gives you. A percentage is simply a fraction out of 100, which is exactly what makes comparisons so easy.
In this lesson you will learn to find a percentage of an amount, write one quantity as a percentage of another, and handle percentage increases and decreases with confidence. You will then meet the two ideas examiners love to test: the difference between simple and compound interest, and reverse percentages, where you work backwards from the final amount to the original. Master these and a whole class of exam questions becomes routine.
