00:00:01.250 --> 00:00:06.350
An architect made a model for a building that is to be 154 meters tall.
00:00:07.250 --> 00:00:13.330
Given that the model is 27.5 centimeters tall, determine the scale of the model.
00:00:14.980 --> 00:00:20.400
The scale will be something like this: every centimeter equals blank meters.
00:00:21.220 --> 00:00:24.980
We need to see the ratio between centimeters and meters.
00:00:25.790 --> 00:00:28.700
The model is 27.5 centimeters.
00:00:29.500 --> 00:00:32.850
And that represented 154 meters.
00:00:33.720 --> 00:00:39.040
To get rid of the decimal point, I’m gonna multiply the numerator and the denominator by 10.
00:00:39.850 --> 00:00:45.910
And now, I have a relationship of 275 over 1540.
00:00:46.980 --> 00:00:53.610
From there, we can divide the numerator and the denominator by 275.
00:00:53.610 --> 00:00:58.300
275 divided by 275 equals one.
00:00:58.300 --> 00:01:05.860
1540 divided by 275 equals 5.6.
00:01:05.860 --> 00:01:11.420
And that shows us that one centimeter is equal to 5.6 meters.
00:01:12.420 --> 00:01:18.410
The scale of the model is such that every centimeter represents 5.6 meters.
