It is easier to compare two decimals when you have the same number of decimal digits, so an extra zero was written to the right of the digit 7 in the decimal 0.
We are able to do this because 0. It is easier to compare decimals when you have the same number of decimal digits. Thus, we often write extra zeros to the right of the last digit of one of the decimals being compared. These extra zeros are place holders and do not change the value of the decimal.
However, if you inserted a zero between the decimal point and a decimal digit, that would change the value of the decimal. This is shown in the table below:. In Examples 3 and 4, there were some problems in which the two decimals being compared did not have the same number of decimal digits.
In these problems, we wrote one or more extra zeros to the right of the last digit of one decimal so that both decimals would have the same number of decimal digits. In the examples above, we used place-value charts to help us compare decimals. Let's try some examples without place-value charts.
Summary: To compare two decimals, start at the left and compare digits in the same place-value position. It is helpful to write one decimal below the other. It is also easier to compare decimals when you have the same number of decimal digits. Thus, when comparing two decimals, we can write one or more extra zeros to the right of the last digit of one decimal so that both decimals have the same number of decimal digits.
You may write one decimal below the other on paper to help you compare. By signing up, you agree to receive useful information and to our privacy policy. Shop Math Games. Practice Problems Step-by-Step Solutions. Together we will look at numerous examples of comparing and ordering decimals in either ascending or descending order.

Which is greater, Which is smaller, Solution: For each of these decimals the integral part is the same. So compare the tenths place. This is also same, check the hundredths places that is also same then move to the next decimal place.
Therefore, Find the greater number; Solution: Which number is greater Arrange the following decimal numbers in ascending order.
The greatest integral part is 9. So, 9. So, 2. In 5th Grade Decimals Worksheet contains various types of questions on operations on decimal numbers. The questions are based on formation of decimals, comparing decimals, Converting Fractions to Decimals, Addition of decimals, subtraction of decimals, multiplication of.
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. Division of a decimal number by 10, or can be performed by moving the decimal point to the left by as many places as the number of zeroes in the divisor.
The rules of division of decimal fractions by 10, , etc. Addition of decimal numbers are similar to addition of whole numbers. We convert them to like decimals and place the numbers vertically one below the other in such a way that the decimal point lies exactly on the vertical line. Add as usual as we learnt in the case of whole. From the above chart we can observe that first we have to work on "P or Parentheses" and then on "E or Exponents", then from. Solve the questions given in the worksheet on decimal word problems at your own space.
This worksheet provides a mixture of questions on decimals involving order of operations. Practice the math questions given in the worksheet on dividing decimals. Divide the decimals to find the quotient, same like dividing whole numbers. This worksheet would be really good for the students to practice huge number of decimal division problems. To divide a decimal number by a whole number the division is performed in the same way as in the whole numbers.
We first divide the two numbers ignoring the decimal point and then place the decimal point in the quotient in the same position as in the dividend. We will practice the questions given in the worksheet on multiplication of decimal fractions.
While multiplying the decimal numbers ignore the decimal point and perform the multiplication as usual and then put the decimal point in the product to get as many decimal places in. 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.
The rules of multiplying decimals are: i Take the two numbers as whole numbers remove the decimal and multiply.
