-
0:00 - 0:05لنرى ان كان بامكاننا تحويل العدد 59.2 و هي نسبة مئوية
-
0:05 - 0:08او %59.2 كرقم عشري
-
0:08 - 0:10بما ان نسبة 59.2 هي نسبة مئوية
-
0:10 - 0:14مما يعني انها تعني 59.2 لكل سنت
-
0:14 - 0:18او 59.2 لكل مئة
-
0:18 - 0:23او 59.2 لكل مئة
-
0:23 - 0:29و هي مساوية ل 59.2 مقسومة على 100
-
0:29 - 0:31اذا قسمنا العدد 59.2 على 100
-
0:31 - 0:32على ماذا سنحصل ؟
-
0:32 - 0:38...
-
0:38 - 0:41فاذا اخذنا العدد 59.2
-
0:41 - 0:42وقسمناه على العدد 10
-
0:42 - 0:44سنحرك الفاصلة العشرية
-
0:44 - 0:45مرة الى اليسار
-
0:45 - 0:46مما سيجعلنا سنحصل على 5.92
-
0:46 - 0:47ولكننا نريد تقسيمها على 100
-
0:47 - 0:49ولذلك سنحرك الفاصلة العشرية
-
0:49 - 0:50مرة اخرى الى اليسار
-
0:50 - 0:51مما يعني اننا قسمنا العدد على 10
-
0:51 - 0:53ومن ثم قسمناه على 10 مرة اخرى
-
0:53 - 0:54بالقسمة على 10 مرتين
-
0:55 - 0:56و هي مساوية لحاصل القسمة على 100
-
0:58 - 1:02ولذلك نحصل على 0.5992
-
1:02 - 1:03و سنضع الصفر هنا
-
1:03 - 1:04للتوضيح
-
1:04 - 1:05و هكذا انتهينا
-
1:05 - 1:08كتبنا النسبة المئوية 59.2 كعدد عشري
-
1:08 - 1:11نحن قمنا فقط بقسمة العدد على العدد 100
-
1:11 - 1:13و ذلك بقسمة العدد على عشرة مرتين
-
1:13 - 1:15و من ثم تحريك الفاصلة العشرية مرة واحدة الى اليسار
-
1:15 - 1:16ومن ثم تحريك الفاصلة مرة اخرى
-
1:16 - 1:17أو بعد قسمة العدد على 100
-
1:17 - 1:19فاننا حركنا الفاصلة العشرية مرتين الى اليسار
-
1:19 - 1:23مما جعل الناتج هو 0.592
