WEBVTT 00:00:00.228 --> 00:00:04.714 試以點數表達16/21這個分數 00:00:04.852 --> 00:00:06.355 我們可以稱這個爲21分之16 00:00:06.370 --> 00:00:09.185 代表16除21 00:00:09.339 --> 00:00:12.610 00:00:12.718 --> 00:00:14.582 因為21比16大, 00:00:14.613 --> 00:00:17.301 所以得出的答案會比1小。 00:00:17.424 --> 00:00:22.113 00:00:22.205 --> 00:00:25.282 00:00:25.359 --> 00:00:31.216 00:00:31.339 --> 00:00:34.759 00:00:34.759 --> 00:00:36.724 00:00:36.832 --> 00:00:41.727 00:00:41.773 --> 00:00:45.859 00:00:46.166 --> 00:00:52.524 00:00:52.678 --> 00:00:54.529 00:00:54.559 --> 00:00:59.562 00:00:59.686 --> 00:01:03.651 00:01:03.682 --> 00:01:07.271 00:01:07.348 --> 00:01:10.570 00:01:10.586 --> 00:01:13.240 00:01:13.302 --> 00:01:15.678 00:01:15.678 --> 00:01:17.369 00:01:17.430 --> 00:01:18.755 00:01:18.878 --> 00:01:20.105 00:01:20.151 --> 00:01:22.107 00:01:22.214 --> 00:01:25.953 00:01:26.122 --> 00:01:30.279 00:01:30.587 --> 00:01:31.738 00:01:31.845 --> 00:01:34.769 00:01:34.784 --> 00:01:36.665 00:01:36.695 --> 00:01:38.292 00:01:38.338 --> 00:01:42.468 00:01:42.545 --> 00:01:43.876 00:01:44.015 --> 00:01:45.421 00:01:45.483 --> 00:01:48.290 00:01:48.290 --> 00:01:50.716 00:01:50.808 --> 00:01:53.152 00:01:53.352 --> 00:01:54.541 00:01:54.618 --> 00:01:56.138 00:01:56.199 --> 00:02:00.329 00:02:00.329 --> 00:02:03.791 00:02:03.930 --> 00:02:06.116 00:02:06.301 --> 00:02:09.762 00:02:09.839 --> 00:02:12.269 00:02:12.330 --> 00:02:14.239 00:02:14.531 --> 00:02:17.885 00:02:17.885 --> 00:02:21.315 00:02:21.376 --> 00:02:24.572 00:02:24.633 --> 00:02:28.084 00:02:28.192 --> 00:02:30.152 00:02:30.182 --> 00:02:32.974 00:02:33.036 --> 00:02:38.098 00:02:38.436 --> 00:02:41.135 00:02:41.243 --> 00:02:49.067 00:02:49.343 --> 00:02:52.913 00:02:52.959 --> 00:02:54.925 00:02:55.017 --> 00:02:57.911 00:02:58.126 --> 00:03:01.387 00:03:01.602 --> 00:03:03.957 00:03:04.141 --> 00:03:05.808 00:03:05.993 --> 00:03:09.370 00:03:09.523 --> 00:03:14.400
