Math Grade 1

A numerical quantity that is not a whole number

(e.g. 1/2)

1. Like Fractions:
The fractions having the same denominators are known as like fractions.
We know that fractions such as 2/5, 3/5, 5/5, 7/5, 9/5, etc., are like fractions.

2. The same Numerator Fractions:
The factors having the same numerators are called the same numerator fractions.
Fractions such as 2/5, 2/7, 2/9, 2/11, etc., are same numerator fractions.

3. Unit Fractions:The fractions having one (1) as their numerator are called unit fractions.1/3, 1/5, 1/7, 1/9 etc., are unit fractions.

4. Proper fractions:
A fraction in which the denominator is greater than the numerator is called a proper fraction. We can also say that a fraction with its numerator less than the denominator is known as a proper fraction.
1/2, 2/3, 4/5, 5/6, 7/10, 9/11, 11/21, 35/45, etc., are proper fractions.

5. Improper Fractions:

A fraction in which the denominator is smaller than or equal to its numerator is called an improper fraction. We can also say that a fraction with its numerator greater than or equal to the denominator is known as an improper fraction.

5/3, 9/5, 11/7, 17/8, 21/14, 19/15, etc., are improper fractions.

6. Mixed Fractions:

When an improper fraction is written as a combination of a whole number and a proper number, it becomes a mixed fraction or mixed number.

As: 6/5 = 5 + 1/5 = 5/5 + 1/5 = 1 + 1/5 = 11/5

11/2, 11/4, 23/4, 35/7, 51/9, etc., are mixed fractions.

All types of fraction may be categorized into three kinds, i.e., proper, improper and mixed fraction.
