# Decimal System and Tips on How to Learn Them

Fractional numbers are the numbers that represent parts of a whole. They are the ratio between two integer numbers. Fractions consist of a numerator and a denominator separated by a line. When these fractional numbers are written in a shortened form in powers of tens, it is called a decimal number. A decimal notation is written as two numbers separated by the decimal separator(.) The number before the decimal separator is the whole number, and the number on the right side of it is the part of a number. For example, the fraction 3/2 can be written in the form of decimals as 1.5 where ‘1’ is in one’s place, and ‘5’ is in the tenths place.

Learning decimals is an elementary task. If someone wants to learn decimals in mathematics, here are some tips that will be beneficial:

## Meaning of a Decimal Number:

A decimal number consists of a whole number and a fractional number separated by the decimal symbol. Let us say that you have eight whole apples, and additionally, you have an apple cut in half. Now you have, in total ‘8.5’ apples with you if represented in the decimal notation. Here, the number ‘8’ represents the whole apples that you have, and ‘5’ represents the fraction of a whole apple that is present with you. This fractional part is written in the base of 10.

## Place Values in Decimal System:

The numbers that come after the decimal separator are counted similarly to the ones that come after it. The only difference is that the numbers that come after the decimal are written with the inclusion of the suffix -ths at the end of their placement names. Let us take the example of the number 38.92. Here, the number 8 before the decimal point is on the one’s position. Similarly, 3 is in the tens position. While the number 9 after the decimal point is in the tenths position and 2 is in the hundredths position. The ‘ones’ place value after the decimal doesn’t exist.
