00:00:00.000 --> 00:00:01.885


00:00:01.885 --> 00:00:03.770
עכשיו אראה לכם איך להמיר שבר

00:00:03.770 --> 00:00:04.920
לשבר עשרוני

00:00:04.920 --> 00:00:06.990
אם יהיה לנו זמן, נלמד איך להמיר

00:00:06.990 --> 00:00:08.730
שבר עשרוני לשבר פשוט

00:00:08.730 --> 00:00:11.420
נתחיל עם, מה שבעיני

00:00:11.420 --> 00:00:12.480
היא דוגמא פשוטה

00:00:12.480 --> 00:00:15.210
נתחיל עם השבר 1/2

00:00:15.210 --> 00:00:17.390
ואני רוצה להמיר אותו לשבר עשרוני

00:00:17.390 --> 00:00:20.170
השיטה שאציג לכם תמיד עובדת

00:00:20.170 --> 00:00:22.850
מה שעושים זה שמחלקים את המכנה

00:00:22.850 --> 00:00:24.530
במונה

00:00:24.530 --> 00:00:25.510
נבדוק איך זה עובד

00:00:25.510 --> 00:00:29.110
נקח את המכנה -- שהוא 2 -- ונחלק

00:00:29.110 --> 00:00:32.280
במונה שהוא 1

00:00:32.280 --> 00:00:34.110
ואתם בוודאי שואלים, 
איך מחלקים 2 ב 1?

00:00:34.110 --> 00:00:37.010
אתם בוודאי זוכרים מיחידת
השברים העשרוניים

00:00:37.010 --> 00:00:40.220
אנחנו יכולים להוסיף 
נקודה עשרונית כאן וכמה אפסים

00:00:40.220 --> 00:00:42.880
לא שינינו את ערך המספר
אבל

00:00:42.880 --> 00:00:45.260
אנחנו מוסיפים דיוק

00:00:45.260 --> 00:00:46.700
נוסיף נקודה עשרונית כאן

00:00:50.260 --> 00:00:50.650
האם שתיים נכנס באחת?

00:00:50.650 --> 00:00:51.280
לא.

00:00:51.280 --> 00:00:56.180
2נכנס ב 10, 
אז 2 נכנס ב 10 חמש פעמים

00:00:56.180 --> 00:00:59.060


00:00:59.060 --> 00:01:00.050


00:01:00.050 --> 00:01:01.150


00:01:01.150 --> 00:01:06.675


00:01:10.570 --> 00:01:12.050


00:01:12.050 --> 00:01:15.000


00:01:15.000 --> 00:01:19.190


00:01:19.190 --> 00:01:20.740


00:01:20.740 --> 00:01:25.470


00:01:25.470 --> 00:01:27.800

00:02:06.960 --> 00:02:08.630


00:02:08.630 --> 00:02:09.840


00:02:09.840 --> 00:02:12.410


00:02:12.410 --> 00:02:17.320


00:02:17.320 --> 00:02:25.210


00:02:25.210 --> 00:02:29.770


00:02:29.770 --> 00:02:33.400
