00:00hi kids today we will learn more about fractions first of all we know fractions
00:09are parts of a whole like 1 by 2 is half of a whole and two halves make one whole
00:221 by 4 is a quarter of a whole and four quarters make one whole 1 by 3 is one
00:36third of a whole and three one-thirds make one whole now let's learn what is a
00:47numerator and denominator in a fraction two numerals are written one below the
00:58other separated by a line the numeral written above the line is called
01:06numerator and the numeral written below the line is called denominator let's
01:15take an example here is a fraction 2 by 4 here 2 is the numerator and 4 is
01:27denominator denominator tells us how many equal parts the whole has been
01:36divided into numerator tells us how many parts of a whole are being considered
01:44here so 2 by 4 means 2 parts out of 4 equal parts of a whole now let's learn
01:57what are like fractions fractions that have same denominators are called like
02:07fractions these are all examples of like fractions as they all have same
02:16denominator you can directly compare add subtract and perform other mathematical
02:25operations on like fractions now let's learn what are unlike fractions unlike
02:33fractions fractions that have different denominators are called unlike fractions
02:41these are all examples of unlike fractions you need to convert unlike
02:50fractions to like fractions before comparing adding subtracting and
02:58performing other mathematical operations on them now let's learn what are proper
03:07fractions a fraction where numerator is less than denominator it is called
03:16proper fraction here numerator is less than denominator so it's a proper
03:25fraction all these are examples of proper fractions because in every
03:34fraction numerator is less than denominator now let's learn what are
03:43improper fractions a fraction where numerator is equal or bigger than
03:51denominator it is called improper fraction here the denominator is bigger
03:58than numerator so it's a improper fraction all these are examples of
04:07improper fractions as the numerator is bigger than denominator now let's learn
04:17what are unit fractions fractions where numerator is one or unit are called like
04:28fractions these are all unit fractions as the numerator is one in all the
04:37fractions good so what have we learned we have learned that fractions are parts
04:46of a whole and they are represented by two numbers one above the line and one
04:53below the line the number above the line is numerator and the number below the
05:01line is denominator fractions with smaller numerator are called proper
05:08fractions fractions with equal or bigger numerator are called improper fractions
05:15fractions with same denominators are called like fractions fractions with
05:24different denominators are called unlike fractions fraction with numerator one is
05:32called unit fraction now you may go ahead and take a quiz to learn more bye
