All right, so what you want to do in this problem is look at the third decimal place, because we're doing two places.
00:09
So what you're looking at is this number, and if that number is greater than or equal to 5, which it is, you go to this next digit and you bump it up.
00:19
Well, there's no digit after 9, so what i tell students is to look at the whole of 59, and the next number after 59 is 60.
00:28
So we're looking at 0 .60 for that first answer so if we do the same thing with b where we have 5 .0463 and again we're well this time we're doing three places so we're looking at the fourth digit which is three and that is smaller than five so you look at the previous digit and you leave it alone so we're looking at 5 .046.
01:02
So as i look at the next one, 0 .80729, and this time we're doing four places.
01:14
So i look at the digit after, and 9 is greater than or equal to 5.
01:19
So you go to the previous digit, you bump it up one.
01:22
So one more than two would be three...
