"1.5" in English can be read as "one point five."
This is because the decimal point is used in English to indicate a fractional component of a number. The number to the left of the decimal point represents the integer part of the number, and the number to the right represents the fractional part. For example, "1.5" can be read as "one and a half," with the "1" representing one whole unit and the "0.5" representing half of a unit.
Here are some examples of how "1.5" can be used in English sentences:
"The temperature outside is 1.5 degrees Celsius." (Translation: "外面的温度是1.5摄氏度。")
"I need to buy 1.5 kilograms of apples at the market." (Translation: "我需要在市场上买1.5千克的苹果。")
"The cost of the ticket is $1.5." (Translation: "票价是1.5美元。")
The use of the decimal point to indicate fractions of a unit can be traced back to the ancient Romans, who used a similar system to represent fractions of a pound. The modern use of the decimal point and the concept of the decimal number system was developed in the 16th and 17th centuries by mathematicians such as Simon Stevin and John Napier.
