3.45 in English can be read as "three point four five." It is a way of expressing a number with a decimal point.
The use of a decimal point to represent fractions of a whole dates back to ancient civilizations. The concept of using a symbol to represent a fraction of a whole, such as 1/2 or 1/4, has been around for thousands of years. The decimal point as we know it today, however, was not widely used until the late Middle Ages, when it was adopted by mathematicians in Europe.
Here are some examples of how 3.45 might be used in English sentences:
"The cost of the item is $3.45." (这个物品的价格是3.45美元。)
"The temperature outside is 3.45 degrees Celsius." (外面的温度是3.45摄氏度。)
"I ran 3.45 miles this morning." (今天早上我跑了3.45英里。)
