2
00:00:00,490 --> 00:00:07,030
Ποιο ειναι το κοστος 14,6 γαλονιων βενζινης με $2,70

3
00:00:07,030 --> 00:00:08,290
το γαλονι;

4
00:00:08,290 --> 00:00:15,600
Λοιπον εχουμε 14,6 γαλονια, και καθε γαλονι

5
00:00:15,600 --> 00:00:17,300
θα κοστιση $2,70.

6
00:00:17,300 --> 00:00:21,530
η μπορουμε να δουμε $2,70 σαν 2,7 δολλαρια.

7
00:00:21,530 --> 00:00:25,040
Ας πολλαπλασιασουμε επι 2,70.

8
00:00:25,040 --> 00:00:26,870
Κανει τα πραγματα λιγακι πιο απλα.

9
00:00:26,870 --> 00:00:30,490
Νομιζω θα εκτιμησετε οτι $2,70 ειναι το ιδιο με 2,7

10
00:00:30,490 --> 00:00:32,340
δολλαρια το γαλονι.

11
00:00:32,340 --> 00:00:35,030
Ας πολλαπλασιασουμε αυτο.

12
00:00:35,030 --> 00:00:38,620
Πρωτα εχουμε, και ας υπενθυμίσουμε, οταν πολλαπλασιαζεις

13
00:00:38,620 --> 00:00:42,280
δεκαδικους, πρεπει να χειριστης τους αριθμους σαν ολικους

14
00:00:42,280 --> 00:00:44,760
αριθμους και μετα να ανησυχείς για το δεκαδικο μελος.
