Decimal numbers are the part of numbers that have two parts. The decimal numbers are in the standard form representing integer and non-integer numbers. Generally, the decimal points are written in a fraction which consists of 10, 100, 1000 in the denominators. The numbers that are expressed in the decimal form are called decimal numbers. Let us check the complete concept on decimal in the below article.<\/p>\n

A decimal number is a number that has two parts. One part has a whole number and the other part is a fractional part. Both parts are separated by decimal points. If 2.48 is a decimal number, then 2 is the whole number and 48 is the fractional part. “.” is the decimal point.<\/p>\n
Examples:<\/p>\n
(i) In the decimal number 47.25, the whole number part is 47 and the decimal part is .25
\n(ii) In the decimal number 89.063, the whole number part is 89 and the decimal part is .063
\n(iii) Take the decimal number 11.056 where the whole number part is 11 and the decimal part is .056<\/p>\n
Decimal numbers are classifieds into different types. They are given with definitions and examples explained in detail.<\/p>\n
Recurring Decimal Numbers<\/strong> – Recurring Decimal Numbers are Repeating or Non-Terminating Decimals. Non-Recurring Decimal Numbers<\/strong> – Non-Recurring Decimal Numbers are Non Repeating or Terminating Decimals. Decimal Fraction<\/strong> – Decimal Fraction is the fraction that consists of the denominator as powers of ten. Converting a Decimal Number into Decimal Fraction<\/strong> Examples: Place value of a number in decimals is the position of every digit that helps to find its value. The position of each digit that before and after the decimal point is different. Check out the below examples to know each digit’s place value<\/a>.<\/p>\n Examples: As each digit, we move to the left side the value becomes 10 times greater than the previous value.<\/p>\n If we consider a decimal number, the digits after the decimal points will become 10 times smaller than other digits. The digits present on the left side of the decimal are multiplied with the positive powers of ten in increasing order from right to left. The digits present in the right of the decimal point are multiplied with the negative powers of 10 in increasing order from left to right.<\/p>\n Example: We have given the main properties of the decimal numbers below those are under multiplication and division operations. Check out all the properties of decimals given below.<\/p>\n We can perform addition, subtraction, multiplication, and division operations on Decimals easily. Check out the below concepts to understand different Arithmetic Operations on Decimals.<\/p>\n Addition Operation on Decimals<\/strong> Subtraction Operation on Decimals<\/strong> Multiplication Operation on Decimals<\/strong> Division Operation on Decimals<\/strong> We consider the digits after the decimal point as the tenths, hundredths, thousandths, and so on. Write down the decimal numbers in the expanded form and simplify the values. To convert the fraction number into a decimal number, divide the numerator by denominator.

\nExamples of Recurring Decimal Numbers are 2.123123 (Finite) and 4.252525252525… (Infinite)<\/p>\n
\nExamples of Non-Recurring Decimal Numbers are 5.14812 (Finite) and 2.5428454845…. (Infinite)<\/p>\n
\nExamples are 72.66 = 7266\/100 and 43.536 = 43536\/1000.<\/p>\n
\nTo convert the Decimal Number into Decimal Fraction, place the 1 in the denominator and remove the decimal point from the given number. The 1 is followed by the number of zeros that are equal to the number of digits given after the decimal point.<\/p>\n
\n1. 47.59
\nThe given decimal number is 47.59
\n47.59 = 4759\/100
\n4 represents the power of 101 that is the tenths position.
\n7 represents the power of 100 that is the unit’s position.
\n5 represents the power of 10-1 that is the one-tenth position.
\n9 represents the power of 10-2 that is the one-hundredths position.
\nSo that is how each digit is represented by a particular power of 10 in the decimal number.
\n2. 61.27
\nThe given decimal number is 61.27
\n61.27 = 6127\/100
\n6 represents the power of 101 that is the tenths position.
\n1 represents the power of 100 that is the unit’s position.
\n2 represents the power of 10-1 that is the one-tenth position.
\n7 represents the power of 10-2 that is the one-hundredths position.
\nSo that is how each digit is represented by a particular power of 10 in the decimal number.<\/p>\nPlace Value in Decimals<\/h3>\n
\nLet us take a number 296.<\/p>\n\n

Arithmetic Operations on Decimals<\/h3>\n
\nWhen you add two decimal numbers, line up the decimal points of the given numbers and add them. If you don’t see a decimal point, then that is only a whole number.<\/p>\n
\nSubtraction Operation on Decimals is also similar to the Addition Operation on Decimals. You need to line up the decimal point of the given numbers and subtract the values.<\/p>\n
\nMultiplication Operation on Decimals is like integers as if the decimal point not present. Firstly, find out the product and count the number after the decimal point in the given numbers. The count will let you know how many numbers present after the decimal point in the result.<\/p>\n
\nThe Division Operation on Decimals is simply dividing the given two decimal numbers. Move the decimal points to make them whole numbers. Then, perform the division operation like normal integers.<\/p>\nDecimal to Fraction Conversion<\/h3>\n
\nExample:
\nLet us consider a decimal number 5.21
\nConver it into a fraction number.
\nThe expanded form of 5.21 is 521 x (1\/100) = 521\/100.<\/p>\nFraction to Decimal Conversion<\/h3>\n
\nExample: 9\/7 is a fraction. If it is divided, we get 1.285714<\/p>\nDecimal Problems with Solutions<\/h3>\n
\nSolution:
\nGiven fraction number is 6\/10.
\nTo convert fraction to decimal, divide 6 by 10, we get the decimal form.
\nThus, 6\/10 = 0.6
\nHence, the decimal form of 6\/10 is 0.6.<\/p>\n
\nSolution:
\nThe given decimal number is 2.36
\nThe expanded form of 2.36 is
\n= 236 x (1\/100)
\n= 236 \/100
\n= 118\/50
\n= 59\/25
\nHence, the equivalent fraction for 2.36 is 59\/25.<\/p>\nFrequently Asked Questions on Decimals<\/h3>\n
