  • In the previous session, we learned about fractions and decimals, as well as the operations of addition and subtraction on them.

  • Multiplication and division operations on fractions and decimals are now being studied.

  • We've learnt the art of multiplying fractions. When two fractions are multiplied, the numerators and denominators are multiplied separately, and the product is written as the product of numerators by product of denominators. For example, $\dfrac{1}{2}\times \dfrac{3}{2}=\dfrac{3}{4}$

  • A fraction serves as a ‘of' operator, like,$\dfrac{3}{4}$of $2=\dfrac{3}{2}$.

  1. The product of two correct fractions is less than the product of the multiplied fractions.

  2. A proper and an improper fraction's product is smaller than the improper fraction and bigger than the appropriate fraction.

  3. The sum of two improper fractions is larger than the sum of the two fractions.

  • By inverting a fraction upside down, you can get its reciprocal. We've already looked at how to divide two fractions.

  1. When dividing a whole number by a fraction, the reciprocal of the fraction is multiplied by the whole number. For example, $3\div \dfrac{1}{2}=3\times 2=6$

  2. When dividing a fraction by a whole number, the reciprocal of the whole number is multiplied by the fraction. For example,$\dfrac{3}{4}\div5=\dfrac{3}{4}\times \dfrac{1}{5}=\dfrac{3}{20}$.

  3. We multiply the first fraction by the reciprocal of the other while dividing one fraction by another fraction. As a result,  $\dfrac{3}{4}\div \dfrac{5}{2}=\dfrac{3}{4}\times \dfrac{2}{5}=\dfrac{3}{10}$.

  • We learned how to multiply two decimal values as well. Multiply two decimal numbers as whole numbers first before multiplying them as decimal numbers. In both the decimal figures, count the number of digits to the right of the decimal point. Add the total number of digits you've counted. Count the digits from the rightmost spot in the product to get the decimal point. The total acquired before should be used as the count. For example,$0.3\times 0.4=0.12$.

  • To multiply a decimal value by $10,100$ or $1000$we move the decimal point to the right by as many places as the number of zeros over one. For example, $0.24\times 10=2.4,$

$0.24\times 100=24,$

$0.24\times 1000=240.$

  • We've already looked at how to divide the decimal numbers.

  1. To divide a decimal number by a whole number, we must first divide the two values into whole numbers. Then, as with the decimal number, place the decimal point in the quotient. For example,$1.2\div 2=0.6$.

It's worth noting that we're only looking at divisions with a zero remainder.

  1. To determine the quotient when dividing a decimal number by $10,100$ or $1000$, shift the digits in the decimal number to the left by as many places as there are zeros over $1$. For example, 

$12.8\div 10=1.28$,

$12.8\div 100=0.128,$

$12.8\div 1000=0.0128$

  1. To convert the divisor to a whole number when dividing two decimal values, shift the decimal point to the right by an equal number of places in both. After that, split. Thus, $3.6\div 0.3=12$

Fraction word is taken from the Latin word “ Fractus” which means broke. Which mainly represent a part of a whole, consisting of a number of equal parts out of a whole. For example, we have a pizza of four equal slices and now we are left with only two slices of pizza. So we can write it in fractional form as 2/4 or ½. Here 2 or 1 is a numerator and 4 or 2 is a denominator. The numerator tells us about the left pizza slices and the denominator tells us about the total number of pizza slices. So in general fraction form is written as a numerator/denominator, Where, denominator ≠ 0. In case the numerator is equal to the denominator then the fraction becomes a whole i.e. 1. This is termed as a unity of fraction.

Types of Fraction

Mainly there are six types of fractions. All these types of fraction are discussed below:

1. Proper Fraction: In this fraction, the numerator is always less than the denominator. It shows the part of a whole.

2. Improper Fraction: In this fraction numerator is always more than the denominator and it shows the mixture of whole and a proper fraction.

3. Mixed Fraction: In this type of fraction we write mixed form as it is the mixture of whole numbers and a fraction.

4. Like Fraction: In this type, there are fractions with the same denominator. 

5. Unlike Fraction: In this fraction, there are fractions with different denominators. 

6. Equivalent Fraction: The fraction which is proportional to each other is termed as an equivalent fraction. 


Numbers that are generally used to represent numbers that are smaller than the unit 1 are termed as decimal. It is also known as the base 10 system since each place value is denoted by a power of 10.

When we multiply a decimal number with the whole number then we get the same number of digits after the decimal point as that of the decimal number.

E.g : 22.2×4 = 88.8

When we multiply decimal with power of 10, then in that case the decimal point shifts to the right by the number of zeros in its power.

Example: 22.22 × 100 = 2222

When we multiply the decimal with decimal, then they will give decimal points in the answer as many places are the same as the total number of places right to the decimal points in both numbers.

Example: 22.22 × 2.2 = 48.884

FAQs on Fractions and Decimals Class 7 Notes CBSE Maths Chapter 2 (Free PDF Download)

1. What are some of the uses of fractions and decimals?

Fractions and decimals are used in many different ways in mathematics and everyday life. Here are a few examples:

  • Fractions are used to represent parts of a whole. For example, you can use fractions to represent the number of slices of pizza you have eaten.

  • Decimals are used to represent numbers that are not whole numbers. For example, you can use decimals to represent the temperature in degrees Celsius.

  • Fractions and decimals are used in many different formulas in mathematics. For example, you can use fractions to represent the slope of a line or the area of a triangle.

  • Fractions and decimals are used in everyday life to represent quantities such as money, weight, and volume. For example, you can use fractions to represent the amount of change you have received or the amount of liquid in a container.

2. How do we add and subtract fractions?

To add or subtract fractions, we first need to make sure that the fractions have the same denominator. Once the fractions have the same denominator, we can simply add or subtract the numerators. For example, to add 1/2 and 1/4, we would first need to make sure that both fractions have the same denominator. We can do this by multiplying 1/2 by 2/2, which gives us 2/4. Now that both fractions have the same denominator, we can simply add the numerators: 2/4 + 1/4 = 3/4.

To subtract fractions, we would follow the same procedure as adding fractions, but instead of adding the numerators, we would subtract them.

3. How do we multiply and divide fractions?

To multiply fractions, we simply multiply the numerators and the denominators. For example, to multiply 1/2 by 3/4, we would multiply the numerators 1 and 3, and the denominators 2 and 4. This gives us 3/8.

To divide fractions, we flip the second fraction and multiply. For example, to divide 1/2 by 3/4, we would flip the second fraction, 3/4, to get 4/3, and then multiply 1/2 by 4/3. This gives us 4/6, which can be simplified to 2/3.

4. What are repeating decimals?

Repeating decimals are non-terminating decimals where a certain group of digits repeats itself over and over again. For example, 0.33333333... is a repeating decimal where the group of digits 333 repeats itself.

Repeating decimals can be converted to fractions by using a process called "decimals to fractions".

Here are the steps to convert repeating decimals to fractions:

  • Write the repeating decimal as a fraction with a denominator of 10.

  • Multiply the numerator and denominator of the fraction by the number that is formed by repeating the group of digits after the decimal point.

  • Simplify the fraction.
