00:00hi kids we now know when to use division now we will learn how to divide any
00:09number with multiples of ten like ten one hundred thousands so let's get
00:18started we have to divide 20 by 10 so we can
00:25write it like this in order to divide with 10 we have to cut a rightmost zero
00:34from numerator and denominator and you are left with 2 by 1 and any number
00:45divided by 1 is same number or 2 by 1 equals 2 so 20 by 10 is 2 by 1 equals 2
01:00now let's take another example we have to divide 200 divided by 100 we write it
01:13like this now in order to divide with 100 we have to cut the two rightmost
01:22zeros from numerator and denominator and you are left with 2 by 1 and any number
01:33divided by 1 is the same number so 200 by 100 equals 2 by 1 is 2 now let's take
01:47another example now let's divide 200 by 10 in order to divide with 10 we have to
01:58cut the rightmost zero from numerator and denominator so we are left with 20 by
02:071 or 20 so 200 by 10 equals 20 by 1 equals 20 now let's take another example
02:22now let's divide 4,000 by 100 in order to divide with 100 we have to cut the
02:32two rightmost zeros from numerator and denominator so we are left with 40 by 1
02:41so 4,000 by 100 equals 40 by 1 equals 40 now let's take another example let's
02:56divide 2003 by 100 in order to divide with 100 we have to cut the two
03:06rightmost zeros from the numerator and denominator but here we don't have zeros
03:15at rightmost places in 2003 so what should we do here we put a decimal after
03:25two digits from right in the numerator so what we did here to cut two zeros of
03:36denominator we put decimal after two digits from right in the numerator and
03:42we are left with 20.03 by 1 so 2003 by 100 equals 20.03 by 1 is 20.03 now let's
04:02take more such examples to learn more now let's divide 345 by 10 in order to
04:14divide with 10 we have to cut the rightmost zero from the numerator and
04:19denominator but here we don't have a zero at the rightmost place in the
04:26numerator so what should we do here whenever we don't have zeros to cut we
04:32can put decimal after the same number of digits from the right so we will put a
04:39decimal after one digit from the right like this so what did we do here to cut
04:49zero of denominator we put decimal after one digit from right in the
04:55numerator and we are left with 34.5 by 1 so 345 by 10 equals 34.5 by 1 equals
05:1034.5 now let's take more such examples now let's divide 4567 divided by 1000 in
05:25order to divide by thousand we need to cut three zeros from the numerator and
05:31denominator but we do not have zeros in the rightmost place in the numerator so
05:38what do we do here we can put decimals in the numerator after three digits from
05:46the right so after cutting three zeros in the denominator and putting decimals
05:53in the numerator after three digits from the right we get four point five six
06:00seven so four thousand five hundred and sixty seven divided by 1000 equals four
06:08point five six seven now let's take another example now how do we divide 23
06:19by 1000 to cut three zeros of denominator we need to put decimal after
06:28three digits from the right in the numerator but we don't have three digits
06:35in the numerator in that case put zero at the leftmost place in the numerator
06:42as putting zeros to the left of the number does not change the number so
06:48make it 0 2 3 now put decimal after three digits from the right so we are
06:56left with point 0 2 3 by 1 equals point 0 2 3 so point 0 2 3 is our answer let's
07:10divide 4 by 100 in order to divide by 100 we need to cut two rightmost zeros
07:20from the numerator but there are no zeros in the rightmost places in the
07:27numerator so what will we do here instead of cutting zeros we can put
07:35decimals after two digits from the right in the numerator but again we do not
07:42have two digits in the numerator so what can we do here we can put zero at
07:52leftmost place in the numerator as putting zeros at the leftmost places in
07:58the number does not change the number so we can write it like 0 4 by 100 and now
08:06we can cut the two zeros of the denominator and put decimal after two
08:12digits from right in the numerator so we got point 0 4 by 1 so our answer is 0 4
08:25so we learned 4 divided by 100 equals point 0 4 so kids now let's see some
08:36quick examples 5 by 100 equals 0 5 by 100 equals point 0 5 by 100 is point 0
08:525 345 by 1,000 equals point 345 by 1,000 is point 345 4,500 by 1,000 equals
09:154,500 by 1,000 equals 45 by 10 equals 4.5 by 10 is 4.5 so kids today we have
09:33learned how can we divide numbers with multiples of 10 now you may go ahead and
09:39take a quiz to learn more bye bye
