Select the problem that can be solved by the addition equation 26 plus 12 equals 38.
00:00:11.960 --> 00:00:16.920
In the morning, 26 boats set sail from a harbor.
00:00:17.560 --> 00:00:25.120
In the afternoon, 12 times as many boats set sail than in the morning.
00:00:25.720 --> 00:00:28.400
How many boats set sail in the afternoon?
00:00:28.960 --> 00:00:34.000
Or in the morning, 26 boats set sail from a harbor.
00:00:34.560 --> 00:00:38.440
In the afternoon, 12 more boats set sail.
00:00:39.000 --> 00:00:41.680
How many boats are sailing by the afternoon?
00:00:42.120 --> 00:00:53.520
The question is asking which problem matches the addition equation 26 add 12 equals 38.
00:00:54.160 --> 00:00:59.480
Both problems begin with 26 boats in the harbor in the morning.
00:00:59.920 --> 00:01:09.960
The first problem tells us that, in the afternoon, 12 times as many boats set sail than in the morning.
00:01:10.680 --> 00:01:15.520
That would mean timesing or multiplying 26 by 12.
00:01:16.080 --> 00:01:20.440
But our addition equation means we need to add 12.
00:01:21.000 --> 00:01:32.040
The second problem tells us there were 26 boats in the morning, and in the afternoon 12 more boats set sail.
00:01:32.600 --> 00:01:41.240
26 add 12 is another way of saying 26 and 12 more.
00:01:41.760 --> 00:01:49.520
So this is the problem which matches the addition equation 26 add 12.
