Hello students, let's discuss the question.
00:03
Here we have to convert the binary to octal.
00:07
Now the octal ranges between 0 to 7.
00:13
So here this binary can be represented as 1.
00:20
There are 4 1 and octal is 0 to 7 so we will make the group of 3 1 and we'll add 0 on the left side.
00:34
Now this is represented as inoctal as 7.
00:42
This is as 7 and this is as 3.
00:46
How we have computed? see 1 -1 -1 this can be written as see in octal we have 3 places.
00:57
First place is 2 to the power 0 this is 2 to the power 1 and this is 2 to the power 2.
01:04
2.
01:06
This is the bine.
01:08
This is the octal.
01:11
So here when we have put 1 1 1, 1, so it means that when 1 is multiplied by 2 to the power 0, then it is 1 plus 1 is multiplied by 2 to the power 1, then we get 2.
01:27
And when this is multiplied by 2 the power 2, we get 4.
01:31
This is equal to 7.
01:32
So in the octal form, triple 1 represented as 7.
01:37
And similarly in the case of 011, we'll get 0 multiplied by 2 to 32x2 plus 1 multiplied by 2 to 3 % plus 1 multiplied by 2 to 3 .0 is equal to 3 .7.
01:53
So the answer of the first part is 3 .77.
01:57
This is the octal representation.
02:00
Now in the next part we have to find the binary of this to 3.
02:03
Decimal.
02:05
Now this can be written as 1 .010.
02:09
Now in the binary form we have 1 010.
02:15
Now in this place we have 2 .50 power 0, 2 to the power 1, 2 to the power 2 and 2 to the power 3.
02:24
Now on multiplication 1 to the 1 multiplied by 2 to the power 3 plus 0 multiplied by 2 to the power 2 plus 1 multiplied by 2 to the power 2 plus 0 multiplied by 2 to the power 1 plus 0...
