Cách sử dụng
The word 'percentage' is used to talk about a part or portion of something in relation to the whole amount. For example, if you have a cake and you cut a slice that is one-quarter of the whole cake, then that slice is 25% of the cake. Percentages can be used in many different situations, such as to talk about discounts on prices, scores on tests, or amounts of ingredients in a recipe. To calculate a percentage, you need to divide the part by the whole and multiply by 100. For example, if you got 8 out of 10 questions correct on a quiz, then your score is 80%, because you divide 8 by 10 and multiply by 100. It's important to understand percentages because they are used in many aspects of daily life, such as shopping, banking, and understanding statistics.
