00:00Hi kids! Today we will learn more about division with multiples of 10.
00:10In our last lesson, we learned how we can divide numbers with multiples of 10, hundreds, thousands.
00:21Today we will learn how we can divide numbers with multiples of 10, 20, 30, 40, 50, 200, 400, 5000.
00:36So let's get started!
00:39We have to divide 40 by 20.
00:43First, we can cut zeros as both numbers have the same number of zeros.
00:51Now, divide 4 by 2.
00:56Reducing the fraction to its standard form, we get 2 by 1.
01:04And we know 2 by 1 equals 2, so 40 divided by 20 equals 2.
01:14Now, let's take another example.
01:18Let's divide 60 by 30.
01:23First of all, we can cut the zeros as there are equal numbers of zeros in the numerator and denominator.
01:34Now, let's divide 6 by 3 or reduce 6 by 3 to its standard form.
01:42We get 2 by 1 and we know 2 by 1 is the same as 2.
01:50So, 60 by 30 equals 2.
01:56Now, let's take another example.
02:01Divide 3000 by 30.
02:05First of all, we can cut one zero each from numerator and denominator.
02:13Now, we are left with 300 by 3.
02:20So, we have to divide 300 by 3.
02:24Reduce this fraction to its standard form.
02:30Divide 3 by 3 without taking care of zeros.
02:36Divide 3 by 3, we get 1.
02:40It becomes 100 by 1.
02:43And 100 by 1 equals 100.
02:48Let's take another example.
02:51Divide 450 by 10.
02:57Cutting one zero each from the numerator and denominator, we get 45 by 1 equals 45.
03:06And, 450 divided by 10 equals 45.
03:15Now, let's take another example.
03:19Let's divide 2000 by 500.
03:24First of all, we cut two zeros each from the numerator and denominator.
03:30And we are left with 20 by 5.
03:33So, divide 20 by 5 or reduce this fraction to its standard form.
03:405 cut 4 is 20.
03:44So, we are left with 4 by 1, which is the same as 4.
03:51So, dividing 2000 by 500, we get 4.
03:57Now, let's take one more example.
04:01Let's divide 2700 by 90.
04:06First of all, cutting one zero each, we get 270 by 9.
04:15So, we have to divide 270 by 9 or reduce it to its standard form.
04:239 cut 3 is 27.
04:27So, we are left with 30 by 1, which is equal to 30.
04:342700 by 90 equals 30.
04:39So, kids, what we learned is, while dividing any number with a multiple of 10 other than 10, hundreds and thousands,
04:49first we cut the equal number of zeros from the numerator and denominator.
04:55And then reduce the fraction to its standard form.
05:00And what we get is the answer.
05:04Kids, now you may go ahead and take a quiz to learn more.
05:09Bye-bye.
