1
00:00:00,303 --> 00:00:03,046
Pieņemsim, ka mums ir 9/10,

2
00:00:03,046 --> 00:00:08,046
un mēs gribam pie tām pieskaitīt 1/6.

3
00:00:09,567 --> 00:00:13,039
Kāds būs iznākums?

4
00:00:13,839 --> 00:00:14,827
Varētu likties:

5
00:00:14,827 --> 00:00:16,602
"Te jau ir dažādi saucēji.

6
00:00:16,602 --> 00:00:18,599
Kā tad tos var saskaitīt?"

7
00:00:18,599 --> 00:00:21,038
Un tā arī ir, bet to var atrisināt,

8
00:00:21,038 --> 00:00:23,546
ja atrod kopīgu dalāmo,

9
00:00:23,546 --> 00:00:26,181
par ko pārvērst abus saucējus,

10
00:00:26,181 --> 00:00:28,536
lai tie abiem būtu vienādi.

11
00:00:28,536 --> 00:00:30,498
Kā atrast kopīgu saucēju?

12
00:00:30,498 --> 00:00:32,125
Kopīgs saucējs būs

13
00:00:32,125 --> 00:00:36,478
abu skaitļu, 10 un 6, kopīgs dalāmais.

14
00:00:36,478 --> 00:00:38,638
Kas ir 10 un 6 kopīgais dalāmais?

15
00:00:38,638 --> 00:00:41,436
Mazāko kopīgo dalāmo var viegli atrast,

16
00:00:41,436 --> 00:00:43,502
ja sāk ar lielāko no saucējiem, ar 10.

17
00:00:43,502 --> 00:00:47,312
Vai 10 var dalīt ar 6?

18
00:00:47,952 --> 00:00:50,978
Nevar. Tālāk, vai 20 var dalīt ar 6?

19
00:00:51,588 --> 00:00:56,005
Nē. Vai 30 var dalīt ar 6?
Jā, 30 var dalīt ar 6.

20
00:00:56,005 --> 00:00:57,722
Mēs vienkārši reizinām 10

21
00:00:57,722 --> 00:00:59,556
un meklējam mazāko skaitli,

22
00:00:59,556 --> 00:01:03,644
ko var dalīt ar 6.
Tas būs 30.

23
00:01:03,644 --> 00:01:05,639
Tātad abiem varam dot

24
00:01:05,639 --> 00:01:07,605
saucēju 30.

25
00:01:07,605 --> 00:01:10,296
9/10, kā to pārvērst par daļskaitli

26
00:01:10,296 --> 00:01:11,898
ar saucēju 30?

27
00:01:11,898 --> 00:01:15,984
Sākumā jāsareizina saucējs ar trīs.

28
00:01:17,074 --> 00:01:19,617
Esam sareizinājuši saucēju ar 3.

29
00:01:19,617 --> 00:01:22,088
Ja negribam mainīt daļas vērtību,

30
00:01:22,088 --> 00:01:23,586
jāreizina arī skaitītājs.

31
00:01:23,586 --> 00:01:26,186
Tas arī jāreizina ar 3.

32
00:01:26,996 --> 00:01:29,854
Ja mēs reizinām gan skaitītāju,

33
00:01:29,854 --> 00:01:31,433
gan saucēju ar 3,

34
00:01:31,433 --> 00:01:32,954
daļskaitļa vērtība nemainās.

35
00:01:32,954 --> 00:01:35,751
9 reiz 3 ir 27.

36
00:01:35,751 --> 00:01:38,549
Kā redzi, 9/10 un 27/30

37
00:01:38,549 --> 00:01:40,964
ir viena un tā pati daļa.

38
00:01:40,964 --> 00:01:43,564
Vienkārši tagad tai saucējs ir 30.

39
00:01:43,564 --> 00:01:45,631
Tas ir forši, jotagad varam

40
00:01:45,631 --> 00:01:49,100
piešķirt saucēju 30 arī 1/6.
Ķersimies klāt.

41
00:01:49,100 --> 00:01:51,621
Kāds būs jaunais daļskaitlis?

42
00:01:51,621 --> 00:01:52,724
Vari apturēt video

43
00:01:52,724 --> 00:01:53,850
un padomāt.

44
00:01:53,850 --> 00:01:56,149
Kas jādara ar 6, lai sanāk 30?

45
00:01:56,149 --> 00:01:59,248
Tas jāreizina ar 5.

46
00:01:59,908 --> 00:02:01,628
Ja reizinām saucēju ar 5,

47
00:02:01,628 --> 00:02:04,623
tas pats jādara arī ar skaitītāju.

48
00:02:04,623 --> 00:02:09,623
Tātad, 1 reiz 5 būs 5.

49
00:02:11,008 --> 00:02:13,749
9/10 ir tas pats, kas 27/30,

50
00:02:13,749 --> 00:02:16,453
un 1/6 ir tas pats, kas 5/30.

51
00:02:16,453 --> 00:02:20,226
Tagad beidzot varam saskaitīt,

52
00:02:20,226 --> 00:02:21,817
jo saucēji ir vienādi!

53
00:02:21,817 --> 00:02:23,267
Vienu skaitli trīsdesmito
saskaitām ar otru.

54
00:02:23,267 --> 00:02:25,335
.

55
00:02:25,335 --> 00:02:30,062
Tātad 27/30 plus 5/30.

56
00:02:30,062 --> 00:02:35,062
Sanāk 27 plus 5.

57
00:02:35,471 --> 00:02:40,201
Plus 5 jeb piecas trīsdesmitās.

58
00:02:41,181 --> 00:02:43,583
Plus 5/30.

59
00:02:43,583 --> 00:02:47,361
Kopā sanāk 32/30.

60
00:02:47,361 --> 00:02:50,781
32/30.

61
00:02:50,781 --> 00:02:54,321
Ja gribam, varam šo daļskaitli vienkāršot.

62
00:02:54,801 --> 00:02:56,805
Jāatrod kopīgs dalītājs,

63
00:02:56,805 --> 00:03:00,196
abus var dalīt ar 2.

64
00:03:00,196 --> 00:03:03,505
Dalām skaitītāju un saucēju ar 2.

65
00:03:03,505 --> 00:03:06,118
Skaitītājs dalīts ar 2 ir 16,

66
00:03:06,118 --> 00:03:08,902
saucējs dalīts ar 2 ir 15.

67
00:03:09,452 --> 00:03:12,640
Šis daļskaitlis būs vienāds ar 16/15.

68
00:03:12,640 --> 00:03:16,215
Un ja gribam to pārvērst jauktā skaitlī, 15

69
00:03:16,215 --> 00:03:17,574


70
00:03:17,574 --> 00:03:20,255


71
00:03:20,795 --> 00:03:22,534


72
00:03:22,534 --> 00:03:27,018


73
00:03:27,018 --> 00:03:31,881


74
00:03:31,881 --> 00:03:36,881


75
00:03:36,893 --> 00:03:38,033


76
00:03:38,033 --> 00:03:40,864


77
00:03:40,864 --> 00:03:42,502


78
00:03:42,502 --> 00:03:43,883


79
00:03:43,883 --> 00:03:45,102


80
00:03:45,102 --> 00:03:46,264


81
00:03:46,264 --> 00:03:48,527


82
00:03:48,527 --> 00:03:50,222


83
00:03:50,902 --> 00:03:53,468


84
00:03:53,468 --> 00:03:55,794


85
00:03:55,794 --> 00:03:58,164


86
00:03:58,164 --> 00:04:00,264


87
00:04:00,264 --> 00:04:01,901


88
00:04:01,901 --> 00:04:05,291


89
00:04:05,291 --> 00:04:07,949


90
00:04:07,949 --> 00:04:10,632


91
00:04:10,632 --> 00:04:12,790


92
00:04:12,790 --> 00:04:15,855


93
00:04:15,855 --> 00:04:17,213


94
00:04:17,213 --> 00:04:19,013


95
00:04:19,013 --> 00:04:21,625


96
00:04:21,625 --> 00:04:24,446


97
00:04:24,446 --> 00:04:27,104


98
00:04:27,104 --> 00:04:30,588


99
00:04:30,588 --> 00:04:33,954


100
00:04:34,914 --> 00:04:38,485


101
00:04:38,485 --> 00:04:40,855


102
00:04:40,855 --> 00:04:43,258


103
00:04:43,258 --> 00:04:45,029


104
00:04:45,615 --> 00:04:48,268


105
00:04:48,600 --> 00:04:51,350


106
00:04:52,520 --> 00:04:55,820


107
00:04:56,510 --> 00:05:01,510


108
00:05:02,378 --> 00:05:06,021


109
00:05:06,021 --> 00:05:09,318


110
00:05:10,728 --> 00:05:15,087


111
00:05:15,087 --> 00:05:16,504


112
00:05:16,504 --> 00:05:19,487


113
00:05:19,487 --> 00:05:24,487


114
00:05:24,530 --> 00:05:25,710


115
00:05:25,710 --> 00:05:29,007


116
00:05:29,007 --> 00:05:31,043


117
00:05:31,523 --> 00:05:35,894


118
00:05:36,504 --> 00:05:40,584


119
00:05:41,414 --> 00:05:43,974


120
00:05:43,974 --> 00:05:44,659


121
00:05:44,659 --> 00:05:46,157


122
00:05:46,157 --> 00:05:47,870


123
00:05:47,870 --> 00:05:49,291


124
00:05:49,291 --> 00:05:52,052


125
00:05:52,052 --> 00:05:53,457


126
00:05:53,457 --> 00:05:54,792


127
00:05:54,792 --> 00:05:57,095


128
00:05:57,095 --> 00:05:59,738


129
00:06:00,548 --> 00:06:01,862


130
00:06:01,862 --> 00:06:04,718


131
00:06:04,718 --> 00:06:07,061


132
00:06:07,061 --> 00:06:10,064


133
00:06:10,064 --> 00:06:13,622


134
00:06:13,622 --> 00:06:14,702


135
00:06:14,702 --> 00:06:17,059


136
00:06:17,059 --> 00:06:20,763


137
00:06:20,763 --> 00:06:23,514


138
00:06:23,514 --> 00:06:27,460


139
00:06:27,460 --> 00:06:28,714


140
00:06:29,454 --> 00:06:32,266


141
00:06:32,996 --> 00:06:35,319


142
00:06:35,319 --> 00:06:36,949


143
00:06:36,949 --> 00:06:38,466


144
00:06:38,466 --> 00:06:41,398


145
00:06:41,398 --> 00:06:44,183


146
00:06:44,183 --> 00:06:45,820


147
00:06:45,820 --> 00:06:47,736


148
00:06:47,736 --> 00:06:52,658


149
00:06:52,658 --> 00:06:55,004


150
00:06:55,004 --> 00:06:58,358


151
00:06:58,358 --> 00:06:59,995


152
00:06:59,995 --> 00:07:03,861


153
00:07:04,451 --> 00:07:07,181


154
00:07:07,181 --> 00:07:10,815


155
00:07:10,815 --> 00:07:12,973


156
00:07:12,973 --> 00:07:17,932


157
00:07:17,932 --> 00:07:22,024
