00:00:01.730 --> 00:00:08.910
Use the number line to round 34183 to the nearest ten thousands.
00:00:11.130 --> 00:00:13.200
We have two options for rounding.
00:00:14.690 --> 00:00:21.870
We’ll round 34183 to either 30000 or 40000.
00:00:23.670 --> 00:00:30.740
We can think about rounding by thinking which value is this number closest to on a number line.
00:00:32.290 --> 00:00:40.090
Is 34183 closer to 30000 or 40000 on this number line?
00:00:41.610 --> 00:00:47.830
Halfway between 30000 and 40000 is 35000.
00:00:49.170 --> 00:00:54.510
34183 is less than halfway.
00:00:56.070 --> 00:01:08.900
It is closer to 30000 than it is to 40000 and that means we round 34183 to 30000.
