1

Zenbatki arrazoizkoa zer da?

2

Zer da zenbaki irrizional bat?

3

Zenbaki irrazionalen adibideak:

4

Zenbaki erlazionala nola irudikatzen da zenbaki zuzendarrean?

5

Rasionalen hamartarrak: zein da zehatza eta zein aldizkaria?

6

Hamartarraren aldizkako zenbaki bat zatiki bihurtzea: adibidez 0.(3)

7

Zer da hamartarreko aldakor baten zatiki sortzailea?

8

Zenbaki arrazionalen dentsitatea R-n: dentsuak al dira?

9

Frakzioekin eragiketak: 1/4 eta 1/6 baten batuketa

10

Benetako zenbakien multzoak honako hauek barne hartzen ditu:

Azalpena

Zenbaki errealak a/b moduan adierazi daitezke b≠0 bada.

Zenbaki irrationalek ez dute zatiki zehatzik onartzen eta haien dezimala ez da periodikoa.

√2≈1.414..., π≈3.1416, e≈2.718.

Zenbaki errationalak dentsuak dira zuzenean; bi puntu artean infinitu errational daude.

Zenbaki arrazoizkoak mugatuak edo aldizkakoak izan daitezke.

0.(3) = 0.333... = 1/3.

Hobetzen du hamartar errepikakorra zatiki bihurtzea.

Bi errealeen artean beti dago zenbaki arrazoizkoa.

Baterako izendatzaile komuna 12: 3/12 + 2/12 = 5/12.

Arrazionalak eta arrazionalak ez direnak Egitura Errealaren osagai dira.
