00:09	types of fractions REVIEW . Hello , Children today let
00:16	us revise fractions . A fraction is a part of
00:24	a whole . It represents one or more equal parts
00:29	of a whole object . Look at the Fraction 3/4
00:36	. The number above the line is the numerator .
00:40	It indicates the number of equal parts considered . The
00:45	line is called Fraction bar or division bar . The
00:50	number below the fraction bar is called the denominator .
00:56	It indicates the total number of equal parts the whole
01:00	is divided into kids . A fraction is also a
01:07	part of a set . Look at an example .
01:12	Take a set of four bottles . Three are red
01:16	and one is green . Here , we say ,
01:20	3/4 of the bottles are red . When two or
01:24	more fractions are given , depending on the value of
01:28	their denominators , they can be termed as like or
01:33	unlike fractions like fractions . Fractions with the same denominators
01:40	are called like fractions , for example , one upon
01:46	four , three upon four et cetera . Unlike fractions
01:53	, fractions with different denominators are called unlike fractions ,
01:58	for example , five upon 85 upon three , two
02:04	upon seven et cetera . Now let us revise the
02:09	types of fractions one proper fractions , a fraction in
02:16	which the numerator is less than the denominator is called
02:21	a proper fraction . For example , two is less
02:26	than eight . Thus , we say that to eighth
02:32	is a proper fraction . Two improper fractions , a
02:37	fraction in which the numerator is greater than or equal
02:42	to the denominator is called an improper fraction . For
02:46	example , E five is greater than two . Thus
02:53	, we see that five upon two is an improper
02:58	fraction . B four is equal to four . Thus
03:05	, we see that 4/4 is an improper fraction .
03:11	Three mixed fractions , a mixed number also called as
03:17	mixed fraction is the sum of a natural number and
03:21	a proper fraction . Look at the three circles .
03:26	The 1st and 2nd circles are completely colored , and
03:30	half of the third circle is colored . When added
03:34	. Together , we get 2.5 . This 2.5 represents
03:40	a mixed number here . Number two is the natural
03:45	number , and half is the fraction . Now let
03:50	us change a mixed number to an improper fraction .
03:55	Convert five and three upon nine into an improper fraction
04:01	. To do this , multiply the natural number by
04:05	the denominator and then add the numerator to the product
04:11	to get the new numerator right . The denominator as
04:15	it is therefore five and three upon nine is equal
04:23	to five into nine in brackets plus three upon nine
04:29	, which is equal to 45 plus three upon nine
04:33	that is equal to 48 upon nine . Thus ,
04:38	five and three upon nine is equal to 48 upon
04:44	nine . Next , we will change an improper fraction
04:50	into a mixed number . Look at the given fraction
04:54	to convert into a mixed number . We divide the
04:58	numerator nine by the denominator to we get the cautioned
05:04	as four and the remainder as one . We write
05:09	the mixed number as cautioned , plus remainder upon divisor
05:15	. Thus , nine upon two is equal to four
05:19	plus one upon to which is equal to 4.5 Children
05:27	. Wasn't revising fractions fun .
