00:00:01.570 --> 00:00:07.680
Choose the number that is closest to 110 plus 368.
00:00:10.460 --> 00:00:18.490
To do that, let’s round each of these numbers to their nearest 100.
00:00:18.490 --> 00:00:26.870
We’re going to do that because we notice that all of our interchoices are given in 100s.
00:00:26.870 --> 00:00:37.400
110 rounded to the nearest 100 is 100, the digit in the 10ths place is a one.
00:00:37.660 --> 00:00:39.750
This means we’ll round down.
00:00:41.090 --> 00:00:46.190
110 is closer to 100 than it is to 200.
00:00:48.100 --> 00:00:51.500
We do the same thing with 368.
00:00:51.900 --> 00:01:03.620
We look at our 68 in the 10ths place, and we say that six is greater than five and we need to round 368 up.
00:01:05.360 --> 00:01:11.660
368 is closer to 400 than it is to 300.
00:01:11.980 --> 00:01:13.970
So we round it to 400.
00:01:15.820 --> 00:01:23.700
100 plus 400 equals 500, and 500 is one of our choices.
00:01:25.770 --> 00:01:31.960
500 is the number that is closest to 110 plus 368.
