00:01 Students in this question we have given numbers and we have to round them in 10, 100 and 1000.

00:06 So these are the number 5045, 1100, minus 1552 and minus 4995.

00:19 So and we have to round off these numbers.

00:25 Okay.

00:28 So this will be round off in nearest 10th and here 100 and here 1000.

00:36 Okay.

00:37 So this is 5045.

00:41 Okay.

00:47 So we can calculate that 5045 will be round off to nearest 10th as 5045 .0.

01:02 Okay.

01:03 And this 1100.

01:05 Okay.

01:08 So first of all, we can.

01:09 Okay.

01:14 So, sorry, this is round off to be 10th place, not in the decimal.

01:20 Okay.

01:20 So it will be round off to 5050 because this number will increase by one.

01:27 Okay.

01:28 And now in the 100th place, it will be converted to 5000 because it is less than four and at the thousand, this is zero.

01:39 So it will be also converted to 5000.

01:42 Okay.

01:43 Now the next number is 1100, which can be converted.

01:49 Okay.

01:50 So in the 10th place, we can write that it is zero...
