00:00hi kids today we will learn what are decimals or how to convert fractions into
00:10decimals so let's get started what fraction of this figure is shaded figure
00:22is divided into 10 equal parts and 1 out of 10 equal parts is shaded so 1 10th of
00:35the figure is shaded now we will learn how to convert a fraction number into a
00:44decimal number first of all let's see what are decimal numbers decimal number
00:55is another way of representing a fraction by showing part of the whole by
01:03placing it on the right side of a period like 0.1 here 0.1 represents 1 part out
01:17of 10 parts it is 1 by 10 so we can say 1 by 10 or 0.1 part of this figure is
01:31shaded so 1 by 10 equals 0.1 or 1 10th let's take more example what part of
01:47this figure is shaded here 3 parts out of 10 are shaded in fractions we say
01:58that 3 by 10 of the figure is shaded in decimals we say 0.3 or 3 tenths part of
02:09the figure is shaded let's take another example what portion of the figure having
02:19two circles is shaded here one hole is shaded and in another circle 3 out of 10
02:31parts are shaded so in fractions we can represent it as a mixed number written
02:40like this here 1 represents a whole and 3 by 10 represents the fraction portion
02:51in decimals we can write it like this here 1 represents the whole and 0.3 represents
03:06the three parts of a whole what fraction of this figure is shaded 4 parts out of 10
03:19are shaded so in fractions we will represent it as 4 by 10 and in decimals we can write
03:30as 0.4 or 4 tenths let's take another example what fraction of this figure is shaded 5 parts
03:45out of 10 parts are shaded so in fractions we write it as 5 by 10 and in decimals we
03:57write it as 0.5 or 5 tenths now let's take another example what portion of the figure
04:10having two rectangles is shaded here here one whole rectangle is shaded and in another
04:20rectangle 6 out of 10 parts are shaded so in fractions we can represent it as a mixed
04:29number written like this here 1 represents a whole and 6 by 10 represents the fraction
04:43portion we can name it as 1 and 6 tenths where and separates the whole number
04:56and the fraction number in decimals we can write it like this
05:04here 1 represents the whole and 0.6 represents six parts of the whole
05:14and we read decimal numbers as 1 and 6 tenths here and represents the decimals
05:25and also separates the whole number and the fraction number good so kids today we have
05:36learned what are decimal numbers now you may go ahead and take a quiz to learn more bye
