00:00Hi kids, today we will learn how we can convert improper fractions to mixed fractions and
00:09mixed fractions to improper fractions.
00:13So let's get started.
00:18Let's first learn what are improper fractions.
00:22Fractions where the numerator is equal to or greater than denominator are called improper
00:28fractions.
00:31These are examples of improper fractions as the numerator is equal to denominator.
00:39These are also examples of improper fractions as the numerator is bigger than denominator.
00:47So remember, in proper fractions, numerator is either equal or bigger than denominator.
00:55Any improper fraction can be converted to mixed fraction by dividing the numerator with
01:01denominator.
01:04Let's see how.
01:06Here, we have an improper fraction 5 by 4.
01:12Now let's see how an improper fraction can be converted to mixed fraction.
01:19If we divide 5 with 4, we get 1 as remainder.
01:26What does it mean?
01:28It means, suppose we have to distribute 5 apples among 4 children, then each child will
01:36get 1 whole apple and 1 apple will be again divided among 4 children.
01:45And each child will get 1 fourth of that apple.
01:49So each child will get 1 whole apple and also a slice which is 1 fourth of an apple.
02:00We write the share of each child like this.
02:05Let's see it again.
02:07One quotient means 1 whole apple for each child.
02:12That is, each child will get 1 whole apple for sure.
02:18One remainder means 1 apple will be left and that can be again divided among 4 children.
02:27That is, each child will also get a slice which is 1 fourth of an apple.
02:34So the share of each child is 1 whole apple and a slice which is 1 fourth of an apple.
02:43So 5 by 4 is same as 1, 1 by 4.
02:49Here, 5 by 4 was an improper fraction and we have converted it to mixed fraction.
02:57Let's see more examples of how we convert improper fractions to mixed fraction.
03:03The next fraction is 8 by 6.
03:07We have to convert 8 by 6 to mixed fraction.
03:12Divide the numerator by denominator.
03:16Dividing 8 by 6, we get 1 as quotient and 2 as remainder which means 1 whole number
03:26and 2 will again have to be divided by 6.
03:33That is, if we have to divide 8 things among 6 persons, then each person will get 1 whole
03:39thing and a part which will be 2 by 6 portion of a whole thing.
03:46So we can write it as 1, 2 by 6.
03:51So 8 by 6 is same as 1, 2 by 6.
03:58Let's see another example.
04:00Here is another improper fraction, 35 by 8 which implies dividing 35 objects among
04:108 persons.
04:12If we divide 35 by 8, we get 4 as quotient which means each person will get 4 whole objects.
04:22We also get 3 as remainder which means 3 things will again have to be divided among 8 persons.
04:31So, if we divide 35 objects among 8 persons, each person will get 4 whole objects and remaining
04:423 objects will again have to be divided among 8 persons.
04:47We write it like this, 4, 3 by 8.
04:53So this is mixed fraction for 35 by 8.
04:58Now, let's see how we convert back mixed fractions to improper fraction.
05:05This is a mixed fraction.
05:08If we have to convert it to an improper fraction, denominator will remain the same.
05:16And for numerator, multiply denominator with the whole number and add numerator to it,
05:23like here.
05:26We will multiply 8 with 4 and add 3 to it.
05:318 multiplied by 4 is 32 and adding 3 to it, we get 35.
05:4035 by 8 is the improper fraction for this mixed fraction.
05:47Now let's see another example.
05:50Here we have a mixed fraction.
05:54Let's convert it to improper fraction.
05:57We know denominator remains the same.
06:01And for numerator, we multiply denominator with whole number and then add the numerator
06:07to it, so here.
06:13Multiply 6 with 1 and then add 2 to it.
06:176 multiplied with 1 is 6 and adding 2 to it, we get 8.
06:24So, 8 by 6 is the improper fraction for this mixed fraction.
06:31So kids, now you know what are improper fractions, how to convert them to mixed fraction, and
06:39how to convert that mixed fraction to improper fraction.
06:44Now let's see why improper fractions are so called.
06:50Improper means not proper, that is, they are not proper fractions.
06:57Proper fractions means less than a whole.
07:01And improper fractions denote something which is not less than whole, but they represent
07:07something which is more than a whole.
07:11Now you may go ahead and take a quiz to learn more.
