The representation of a number in the form of a fraction with the base as 10 along with a decimal point is called decimal notation. These digits are from 0-9 that is written in two parts, a whole number and a fractional part that is separated by a dot called the decimal point.
Decimals to Fractions. Because we now have the ability to pronounce decimal numbers, it is a simple exercise to change a decimal to a fraction. 1 For example, 134.12 is pronounced “one hundred thirty-four and twelve hundredths,” so it can easily be written as a mixed fraction. \[134.12 = 134 \frac{12}{100}\nonumber \]
Every rational number can be expressed using decimal notation. To change a fraction into its decimal equivalent, divide the numerator of the fraction by its denominator. In some cases the process will terminate, leaving a zero remainder.
A decimal fraction is a fraction where its denominator is a power of 10 i.e. 10 1,10 2, 10 3 etc. What are Decimal Fractions? The fractions in which the denominator is equal to 10 or multiples of 10 (such as 100, 1000, 1000, 10000, etc.), are known as decimal fractions. Examples: 1/10 = 0.1. 2/100 = 0.02. 7/1000 = 0.007.
Decimal notation is another way to write numbers that are less than 1 or that combine whole numbers with decimal fractions, sometimes called mixed numbers. When you write numbers in decimal notation, you can use an extended place-value chart that includes positions for numbers less than one.
A decimal is a representation of a number that is more (or less) than a whole number. We’ll get into decimal form in a little bit, but essentially, a decimal is a number comprised of three pieces: a whole number piece, a fractional piece, and a dot (a.k.a. the decimal!).
