00:00:01.280 --> 00:00:05.100
Chloe scored 41 points in a sports competition.
00:00:05.720 --> 00:00:10.050
Madison scored 28 points more than Chloe.
00:00:10.850 --> 00:00:14.820
We want to find out how many points Madison scored.
00:00:15.460 --> 00:00:20.120
We can use a part-part-whole diagram to model this problem.
00:00:20.870 --> 00:00:27.370
And then we can answer the questions: is Madison’s score the whole or the other part?
00:00:27.870 --> 00:00:31.110
And how many points did Madison score?
00:00:33.330 --> 00:00:35.920
Here’s our part-part-whole diagram.
00:00:37.300 --> 00:00:41.630
We know that the yellow part represents 28 points.
00:00:42.910 --> 00:00:49.570
We also know that Madison scored 28 points more than Chloe.
00:00:51.310 --> 00:01:00.680
That means Chloe’s points plus 28 points will tell us how many points Madison scored.
00:01:02.030 --> 00:01:06.920
Our problem tells us that Chloe scored 41 points.
00:01:08.250 --> 00:01:12.610
The blue part of our diagram is 41 points.
00:01:15.240 --> 00:01:22.790
And that means that the whole diagram — the blue part and the yellow part — will represent Madison’s points.
00:01:24.190 --> 00:01:27.190
Madison’s score is the whole.
00:01:29.300 --> 00:01:47.640
By finding the sum of the two parts — adding 41 plus 28, we will find how many points Madison scored: one plus eight equals nine, four plus two equals six.
00:01:48.820 --> 00:01:51.670
Madison scored 69 points.
