Hundredths Place in Decimals
When we write a decimal number with two places, we are
representing the hundredths place.
When we divide a square into 100 equal parts, and shade one part out of it, then the shaded part represents one-hundredth of the whole square and is written as 1100. We also write 100 as .01 or 0.01 and read it as 'one hundredth' or 'point zero one' or 'decimal zero one' or 'zero point zero one'.
1. Let us take plane sheet which represents one whole. Now, we divide the sheet into 100 equal parts.
Each part represents one-hundredths of the whole. It is written as 1100. In the decimal form it is written as 0.01. It is read as zero point zero one.
2. Let us represents 20100 on a square sheet.
Now we divide a square into 100 equal parts and shade 20 parts out of it, then shaded parts represent twenty hundredths of the whole square and written as 20100
We also write 20100 as .20 or 0.20 and read it as point two zero or decimal two zero.
3. Let us represents 35100 on a square sheet.
35 parts of hundred equal parts are colored. We write this as 0.35 in decimal form, where 3 represents 3 tenths and 5 represents 5 hundredths. In the place value chart 3 is written in tenths column and 5 is written in the hundredths column.
Similarly, we write 27100, 37100, 95100 as 0.27, 0.37 and 0.95 respectively.
We can also write, 137100 = 1.37,
452100 = 4.52,
5709100 = 57.09 etc.
From the above discussion, we observe that a fraction in the form number100 is written as a decimal obtained by putting point to the left of two right-most digits. If the number is short of digits, we insert zeros to the left of the number.

In converting decimals to fractions, we know that a decimal can always be converted into a fraction by using the following steps: Step I: Obtain the decimal. Step II: Remove the decimal points from the given decimal and take as numerator.
Decimal numbers can be expressed in expanded form using the place-value chart. In expanded form of decimal fractions we will learn how to read and write the decimal numbers. Note: When a decimal is missing either in the integral part or decimal part, substitute with 0.
In dividing decimals word problems worksheet we will get different types of problems on decimals division word problems, dividing a decimal by a whole number, dividing a decimals and dividing a decimals by 10, 100 and 1000.
Dividing Decimals by Decimals I. Dividing a Decimal by a Whole Number: II. Dividing a Decimal by another Decimal: If the dividend and divisor are both decimal numbers, we multiply both the numbers by 10, 100, 1000, etc so that the divisor becomes a whole number
Multiplying decimal by a whole number is just same like multiply as usual. How to multiply a decimal by a whole number? To multiply a decimal by a whole number follow the below steps
Word problems on decimals are solved here step by step. The product of two numbers is 42.63. If one number is 2.1, find the other. Solution: Product of two numbers = 42.63 One number = 2.1
Practice the math questions given in the worksheet on multiplying decimals. Multiply the decimals to find the product of the two decimal numbers, same like multiplying whole numbers.
The working rule of multiplication of a decimal by 10, 100, 1000, etc... are: When the multiplier is 10, 100 or 1000, we move the decimal point to the right by as many places as number of zeroes after 1 in the multiplier.
The rules of multiplying decimals are: (i) Take the two numbers as whole numbers (remove the decimal) and multiply. (ii) In the product, place the decimal point after leaving digits equal to the total number of decimal places in both numbers.
To multiply a decimal number by a decimal number, we first multiply the two numbers ignoring the decimal points and then place the decimal point in the product in such a way that decimal places in the product is equal to the sum of the decimal places in the given numbers.
Here we will learn adding and subtracting large decimals. We have already learnt how to add and subtract smaller decimals. Now we will consider some examples involving larger decimals.
In converting fractions to decimals, we know that decimals are fractions with denominators 10, 100, 1000 etc. In order to convert other fractions into decimals, we follow the following steps:
