All right, so in this problem, perform the calculation and record the answer with the correct number of significant figures.
00:10
All right.
00:11
So now here we have 6 .5 minus 6 .11.
00:16
So let us just do 6 .5 minus 6 .11, which will be giving us value as 0 .39.
00:28
This is basic value, right? i'm not writing exactly the answer right now.
00:32
Okay, now upon 3 .30 is there.
00:37
But you have to just segregate it very clearly for significant figures, right? so here amongst in numerator you can see least number of significant digits is 2 only, that is 6 .5 .1 significant and 2.
00:55
So that means 2 are there.
00:56
That is the least 1.
00:57
And we have here 3.
00:58
So now we have to convert this numerator into as into what two significant digits.
01:06
So it will be 0 .4.
01:09
Is it? so we have rounded off.
01:12
So this becomes 0 .4.
01:14
Now this is divided by again by 3 .30.
01:18
Right.
01:19
So what we are getting right now? so this is for significant figures right, rounding significant figures.
01:27
Okay.
01:28
I'm writing here.
01:34
Okay.
01:35
So now when you divide this, 0 .4 divided by 3 .30, which is giving us 0 .12, right? but this must not be the answer because amongst these two, we have to take that digit which has least, you can say, significant.
02:00
So, significant figure.
02:02
So here you can say that only one significant digits are there because before, point, decimal point, we have 0s are not taking into account for significant figures.
02:16
So the answer becomes equals to after rounding of this becomes point 1.
02:26
Right? so you can say that the answer becomes here point 1 is the correct answer.
02:35
Now moving forward with the same procedure we are doing here.
02:40
So here we have, let us say, let us solve from here...
