# What is submultiple?

## What Does submultiple Mean

The Latin word submultĭplus arrived in Spanish as a submultiple . In the field of mathematics , this is the name of the number that is contained in another twice or more, always exactly .

A submultiple, therefore, is a figure that is found in another an exact number of times. For example: 9 is a submultiple of 45 . If we multiply 9 by 5 , we get 45 as the result. This means that, in 45 , 9 is contained 5 times.
A number is a submultiple of another, in short, when the other contains it exactly two or more times. At the same time, a number is a submultiple of another if this second number is a multiple of the first.

Take the case of the numbers 2 and 20 . Since 2 is contained 10 times in 20 , 2 is a submultiple of 20 . Similarly, 20 is a multiple of 2 since 2 x 10 = 20 .
The idea of a submultiple also appears in the field of measurement units . There are units that are taken as reference units or main units : starting from them, the largest units are called multiples , while the smallest ones are known as submultiples .
The main unit of length is the meter . Following what was expressed in the previous paragraph, there are larger units such as the decameter (dm), the hectometer (hm) and the kilometer (km), which are multiples of the meter. There are also smaller units, such as the decimeter (dm), the centimeter (cm) and the millimeter (mm): they are the submultiples of the meter. It is important to note that the same length can be expressed in meters or in any of its multiples and submultiples.
