Whole Numbers and Decimals
In whole number and decimals we will learn how to represent
a mixed number graphically and write in decimal form.
1. Let us consider a mixed number 1\(\frac{7}{10}\). The number
can be represented graphically as given below.
Here, whole number part is 1 and the decimal part is 7.
The number is written as 1.7 and it is read as one point three. In the placevalue chart 1 is written under ones column and 7 is written in the tenths column.
2. Let us consider an another mixed number 1\(\frac{3}{10}\). The number can be represented graphically as given below.
Here, whole number part is 1 and the decimal part is 3. The
number is written as 1.3 and it is read as one point three. In the placevalue
chart 1 is written under ones column and 3 is written in the tenths column.

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
While comparing natural numbers we first compare total number of digits in both the numbers and if they are equal then we compare the digit at the extreme left. If they also equal then we compare the next digit and so on. We follow the same pattern while comparing the
Decimal numbers can be expressed in expanded form using the placevalue 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, 100 or 1000 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, 100, 1000 etc. are discussed here.
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
Simplification in decimals can be done with the help of PEMDAS Rule. 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
