A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 2140, exactly as in the question.

a decimal fraction means a fraction that changes into a decimal or a decimal that changes into a farction
Well, let's take a moment to appreciate the number 261. As a fraction, 261 can be written as 261/1, which is already in its simplest form. And as a decimal, 261 is simply 261.0, showing its full and complete self. Remember, every number is special in its own way, just like you are special too.
0.21 is a decimal fraction.
0.4 as a fraction and decimal
A decimal number is one in which the place value of each digit is ten times the place value of the digit to its right. (... , thousands, hundreds, tens, units, tenths, hundredths, ... ) A decimal point is used to separate the units from the tenths. If a number in decimal form has non-zero digits after the decimal point then it is a decimal fraction. [There is one esoteric exception: if the decimal point is followed by an infinite string of 9s, then it is not a decimal fraction.] Thus 37.6 is a decimal fraction 0.6 is a decimal fraction 0.00000063 is a decimal fraction 37 is not a decimal fraction. 37.0 is not a decimal fraction. 37.999... recurring is no a decimal fraction [it is in fact = 38].
2140 = 2x2x5x107
That already is a decimal fraction.
It is called a decimal fraction.
930 is not a fraction but as a decimal, it is 930
