高分英语作文1：Expression of percentage

Percentage is a common concept in our daily life. It is used to express the proportion or rate of a certain thing or phenomenon. For example we often say that the unemployment rate in a certain region is 5% or the sales of a certain product have increased by 10% compared with last year. The use of percentage can help to reflect the changes and trends of a certain thing and it is also an important tool for analysis and decision-making.

In mathematics percentage is defined as a fraction with 100 as the denominator. For example 25% can be written as 25/100 or 0.25. We can use percentage to compare different quantities such as the growth rate of two economies the attendance rate of two schools or the success rate of two medical treatments.

However we should also be careful when using percentage. Sometimes a small change in percentage may not reflect the real situation. For example the difference between a 1% and 2% interest rate may seem small but it can make a big difference in the long run. Moreover percentage can be easily manipulated or misused for propaganda or advertising.

In conclusion percentage is a useful tool for expressing proportion and rate but we should use it properly and cautiously. We should always try to understand the context and background behind the percentage and avoid making hasty decisions based solely on percentage.
