Deca- is a prefix in the metric system that denotes a factor of ten. It is derived from the Greek word "deka," meaning ten. In mathematics, deca- is used to indicate a quantity that is ten times larger than the base unit.
Deca- contains the following knowledge points:
To understand deca- in more detail, let's take an example of decameters. The base unit for length in the metric system is the meter. When we add the prefix deca-, it means we are multiplying the base unit by ten. So, one decameter is equal to ten meters.
There is no specific formula or equation for deca-. It is simply a prefix used to indicate a factor of ten.
Since there is no formula or equation for deca-, it cannot be directly applied. However, it is used to convert between different units in the metric system. To apply deca-, you need to multiply the base unit by ten.
For example, if you have a length of 5 meters and want to convert it to decameters, you would multiply 5 by 10. So, 5 meters is equal to 50 decameters.
The symbol for deca- is "da". It is written in lowercase letters and placed before the unit symbol.
For example, decameters is written as "dam", decagrams as "dag", and decaliters as "dal".
The methods for deca- include:
Conversion: Deca- is used to convert between different units in the metric system. To convert from a smaller unit to a larger unit, you multiply by ten. To convert from a larger unit to a smaller unit, you divide by ten.
Measurement: Deca- is used to express quantities that are ten times larger than the base unit. It helps in representing larger measurements in a more convenient and manageable form.
Example 1: Convert 25 grams to decagrams.
Solution: To convert grams to decagrams, we need to multiply by ten. So, 25 grams is equal to 25 * 10 = 250 decagrams.
Example 2: Convert 3 decimeters to meters.
Solution: To convert decimeters to meters, we need to divide by ten. So, 3 decimeters is equal to 3 / 10 = 0.3 meters.
Q: What is the opposite of deca-? A: The opposite of deca- is deci-. Deci- represents a factor of one-tenth in the metric system. It is used to indicate a quantity that is one-tenth of the base unit.
