00:00:01.080 --> 00:00:05.470
Three friends were seeing who could build the tallest tower out of blocks.
00:00:06.000 --> 00:00:08.530
David’s tower was 37 inches high.
00:00:09.040 --> 00:00:13.190
Isabella’s tower was six inches shorter than David’s.
00:00:13.900 --> 00:00:19.400
Ethan built a tower that measured three inches less than Isabella’s.
00:00:19.740 --> 00:00:22.810
How many inches tall was Ethan’s tower?
00:00:25.380 --> 00:00:28.180
This problem gives us a lot of information.
00:00:28.460 --> 00:00:35.820
We need to walk through it one step at a time to find out how many inches tall Ethan’s tower was.
00:00:37.450 --> 00:00:42.400
The first thing we’re told is that David’s tower is 37 inches high.
00:00:44.110 --> 00:00:49.790
We can make a sketch of David’s Tower and mark it as 37 inches high.
00:00:51.500 --> 00:00:59.880
The next piece of information we’re given is that Isabella’s tower is six inches shorter than David’s.
00:01:01.640 --> 00:01:10.110
To find the height of Isabella’s tower, we take the height of David’s tower and subtract six inches.
00:01:11.150 --> 00:01:13.850
David’s tower was 37 inches.
00:01:14.670 --> 00:01:21.010
37 inches minus six inches equals 31 inches.
00:01:22.340 --> 00:01:27.440
Next, we can sketch Isabella’s tower that was 31 inches tall.
00:01:29.040 --> 00:01:36.680
Our last statement tells us that Ethan’s tower is three inches less than Isabella’s.
00:01:37.900 --> 00:01:45.540
Ethan’s tower is the height of Isabella’s tower minus three inches.
00:01:46.540 --> 00:01:50.370
We know that Isabella’s tower was 31 inches tall.
00:01:51.250 --> 00:01:58.290
That means Ethan’s tower is equal to 31 inches minus three inches.
00:01:59.770 --> 00:02:03.800
That makes Ethan’s tower 28 inches tall.
00:02:05.290 --> 00:02:10.380
Ethan’s tower was the shortest and stood 28 inches tall.
