Yes and they are normally written out in descending order.

No, fractions cannot be changed into decimals using Roman numerals. Roman numerals are a numeral system used in ancient Rome, which does not have a way to represent fractions or decimal numbers. Decimal numbers are represented using a base-10 system with digits ranging from 0 to 9.
In decimal we write a number by using a combination of 10 digits (0-9). In base 2, however, numbers are written by using a combination of only 2 digits (0 & 1). We call this number system binary.
Numerals are symbols which are used to write numbers; for example, the Arabic numerals which we use in most situations are simply the ten digits, 0,1,2,3,4,5,6,7,8 and 9. Numbers are many different quantities which can be symbolized by using numerals, such as 657,899.034 or five and a half, or the square root of 2, etc.
Minor Roman numerals are typically used for sub-levels within a larger sequence. The rules for using them include: Minor Roman numerals are always lower case. They are used in descending order from left to right. When a smaller numeral precedes a larger one, it is subtracted from the larger numeral. Minor Roman numerals are typically used for outlining or labeling subcategories within a larger list or sequence.
Roman Numerals are just another way of writing numbers. The same as using the Chinese Numerals, or even our very own Arabic Numerals. Tally is another way of noting numbers. So anything could, in essence, precede or follow Roman Numerals, that could precede or follow Arabic Numerals or Tallies.
A composition is a short essay. Composition also refers to how you structure your writing using the correct grammar rules and rhetoric.
