TYPES OF FRACTION
TYPES OF FRACTION -
So far we have learned about fractions, now we will learn about types of fractions. Types of fractions are described below with their probable examples -
1. Unit Fractions -
Unit fractions are those fractions whose numerator is always 1.
1 1 1 1
Example. - -------, -------, --------, -------
8 10 124 1347
2. Like Fractions -
Like fractions are those fractions which have the same denominator.
3 7 15
Example.- ------, ------, -------
25 25 25
3. Unlike Fractions -
Unlike fractions are those fractions which have different denominator.
37 20 16
Example.- -------, -------, -------
43 17 47
4. Proper Fraction -
A fraction whose numerator is less than the denominator is called a proper fraction. N < D or D > N
(The value of proper fraction is always less than 1.)
12 15 22
Example.- -------, --------, --------
25 18 37
5. Improper Fraction -
A fraction whose numerator is greater than or equal to the denominator is called an improper fraction. N ≥ D, or D ≤ N.
(The value of proper fraction is equal to 1 or greater than 1.)
125 75 61
Example.- -------, -------, -------
29 47 61
6. Mixed Fraction -
A fraction made up of a whole number and a proper fraction is a mixed number or mixed fraction.
15 9 3
Example.- 5-------, 3-------, 7------
17 26 8
For Example - Richard has 5 half apple, and for 5 half apple we can
1 1 1 1 1 5
write -> ---- + ---- + ---- + ---- + ---- = -----
2 2 2 2 2 2
1 1 1 1 1
So, 5 half apples = ----- + ----- + ------ + ------ + ------
2 2 2 2 2
1
= 2 apples + ----- apple remains
2
5 1 1
Therefore, ------ = 2 + ----- = 2----- is a mix fraction
2 2 2
1
2---- is a mixed numeral or a mixed number since part of the numeral
2
is a whole number(2),and part is a fractional number (1/2).
The whole number part is called integral part. The fraction is called fractional part.
