what is the meaning for prefix word deci-
The correct answer and explanation is:
The prefix deci- means one tenth or 0.1 of a unit. It is derived from the Latin word decimus, which means tenth. In the metric system, deci- is used to denote a factor of one-tenth of the base unit. For example, a decimeter is one-tenth of a meter.
The prefix deci- is part of the International System of Units (SI) prefixes, which help express quantities that are smaller or larger than the base unit. When deci- is attached to a unit of measurement, it reduces the size of that unit by a factor of ten. For example:
- 1 deciliter (dL) = 0.1 liters
- 1 decigram (dg) = 0.1 grams
- 1 decisecond (ds) = 0.1 seconds
Using prefixes like deci- allows measurements to be expressed more conveniently and accurately when dealing with quantities that are smaller than the base unit but larger than smaller subdivisions such as centi- (one hundredth) or milli- (one thousandth).
Deci- is less commonly used than some other prefixes like centi- or milli-, but it is still important in various scientific, engineering, and everyday contexts. For example, in medicine, a deciliter is commonly used to measure blood volume or concentration. In length measurements, the decimeter is less common but still used in some countries or specific applications.
In summary, deci- means one tenth and represents a decimal subdivision in measurement systems. It helps communicate values precisely and is a standard prefix within the metric system to indicate that a quantity is divided by ten.
