00:02 Hello guys in this question we have to round the following numbers to three significant figures.

00:16 So first one we have been given is 2359.

00:22 It can be written as 2360 or 236.

00:32 This is the answer.

00:35 Next we have is 1 .2305.

00:41 So when we round it up it will become 1 .3 .5.

00:44 Point two three next is 0 .0 5 0091 it will be equal to 0 .0501 next is 8993256 which is equal to 893 0 0 or we can write it as 8 9 so 89 3 0000 is the correct answer now we have to tell report the measurements with the correct number of the significant figures.

01:35 So we have been given figures and we have to tell the volume, temperature and the length.

01:41 So volume given is equal to 28 .4 ml temperature and length are equal to 20 .75 degrees celsius whereas length is equal to 7 .3 centimeters.

02:03 So this is the answer.

02:06 Now we have to calculate the given answer with the correct number of significant figures.

02:13 The first one we have is 3 .2 .56 divided by 2 .7.

02:20 This will give us 1 .2 and the significant number figures are 2.

02:34 Next we have 14 .88 plus 3 .77.

02:42 This is equal to 566 .56 .56 .1.

02:48 So it it is 14 .88 multiplied by 3 .77 which will give us a value of 56 .1.

02:56 Significant figures are 3...
