Answer the following questions concisely: 1. Why do we need percentages? 2. What are percentages used for real life? 3. What can you do to help yourself understand a question?
1. We use percentages to make calculations easier. It is much simpler to work with parts of 100 than thirds, twelfths and so on, especially because quite a lot of fractions do not have an exact (non-recurring) decimal equivalent.
2. For example, discounts in shops, bank interest rates, rates of inflation and many statistics in the media are expressed as percentages. Percentages are important for understanding the financial aspects of everyday life. Much of what we buy in the shops has a 10% Goods and Services Tax (GST) included in the price.
3. Never ignore the comments of others, this can help you know what you are like.
