All right.
00:01
So they're talking about a library and they want to estimate the number of books they have.
00:06
And so they're going to, they counted up all the different genres and they want to round them each to the nearest hundred and then estimate their total.
00:15
So the hundreds place, remember, is we have the ones, the tens.
00:20
This would be the hundred.
00:21
So we're trying to round to the hundreds place.
00:23
So whatever place you're rounding to, you look one digit to the right.
00:27
And if it's five or more, you round up.
00:31
And if it's less than five, you round down.
00:34
So we're going to have to round our hundreds place up from a one to a two.
00:40
And then all the other places, you make zero.
00:44
So if i round 173 to the nearest hundred, it's closer to 200 than it is to 100.
00:51
And if you think about on a number line, right? i think about, let me go over here.
00:57
I think about on a number line.
00:59
Here's 100.
01:02
Here's 200.
01:05
Halfway would be 150.
01:08
And so where 173 falls is between 150 and 200.
01:14
It's closer to 200 than to 100.
01:17
So when we round it, we would round it to 200.
01:20
When we do the romance novels, four is in the hundreds place.
01:25
When we look to the right, that is less than five.
01:28
So we're going to round that down, which means we're going to keep the hundreds place at a four and make the rest of them zero.
01:36
And again, if we think about our number line, 421 is between 400 and 500.
01:43
It's more than 400, but less than 500...
