Types of Fraction

In Class 7 Mathematics Chapter 2 Notes, six types of fractions are discussed. So let us discover them in detail. 

• Proper fraction: 

In this type of fraction, the value of the numerator is always less than the denominator. It shows the fraction value as a whole. 

• Improper fraction: 

In an improper fraction, the numerator is always greater than the denominator and shows a combination of proper and  whole fraction. 

• Mixed fraction: 

It is a mixture of whole numbers and fractions. 

• Like fraction: 

In a like fraction, the value has the same denominators. 

• Unlike fractions: 

In this type of fraction, they have different values for the denominator. 

• Equivalent fraction: 

These types of fractions are proportional to each other, which is why they are called equivalent fractions.

Decimals

Values that are used to represent numbers that are smaller than unit 1 are known as decimals. It is also known as the base 10 system, as a power of 10 is written in each place. When a decimal number is multiplied by a whole number, we acquire the same number of digits after the decimal point.

For example: 22.2 X 4 = 88.8

If we multiply a decimal number with a power of 10 then the decimal point will shift to the right by the number of zeros in its power.

For example: 22.22 X 100 = 2222

If a decimal divides a decimal number, then one will get the decimal points in the answer at the same places as the total number of places right to decimal positions in both numbers.

Example: 22.22 X 2.2 = 48.884
