They are both ways of representing parts of whole numbers.
Any kind of fraction becomes decimal notation if you divide the denominator into the numerator. Any decimal notation becomes a percent if you multiply it by 100.
a decimal fraction means a fraction that changes into a decimal or a decimal that changes into a farction
To convert a decimal to a fraction, we can write the decimal as a fraction with the decimal as the numerator and a power of 10 as the denominator. In this case, 3.9 can be written as 39/10. To simplify this fraction, we can divide both the numerator and denominator by their greatest common factor, which is 1. Therefore, 3.9 as an improper fraction is 39/10.
To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal as the numerator and a power of 10 as the denominator. In this case, 0.929 can be written as 929/1000. To simplify this fraction, you can divide both the numerator and denominator by their greatest common factor, which in this case is 1. Therefore, 0.929 as a fraction is 929/1000.
First you convert the decimal into a mixed-number/fraction. Then you have to find the common denominator and compare.
0.21 is a decimal fraction.
0.4 as a fraction and decimal
A fraction has a numerator set above its denominator If the numerator is less than the denominator then it is a common fraction as for example 3/4 which as a decimal is 0.75 If the numerator is greater than the denominator then it is an improper fraction as for example 5/4 which as a decimal is 1.25
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].
930 is not a fraction but as a decimal, it is 930
That already is a decimal fraction.
It is called a decimal fraction.
