Choose the number that is closest to 53 plus 83: 200, 300, or 100.
00:00:12.520 --> 00:00:23.440
Before we can choose the number that’s closest to 53 plus 83, let’s estimate 53 plus 83.
00:00:24.400 --> 00:00:33.320
We can round 53 down to 50 and we can round 83 to 80.
00:00:33.880 --> 00:00:37.600
Now we’re asking, what is 50 plus 80?
00:00:38.200 --> 00:00:43.800
Five plus eight equals 13; then we bring over our zero.
00:00:44.200 --> 00:00:54.600
50 plus 80 equals 130, and 130 is closest to 200, 300, or 100.
00:00:55.000 --> 00:01:00.360
100, 130 is closest to 100.
