Mixed Fraction 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).
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.
Unlike Fractions
<i>Fractions with different denominators (bottom numbers) are called unlike fractions.</i>
For example:
(i) ²/₃, ¹⁵/₁₃, ¹²/₁₇ and ³⁵/₁₉ are unlike fractions with different denominators (bottom numbers).
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.
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.
