Question

Aflati partea intreaga si partea fractionara a numerelor : 8,2; -7,2; 2,(5); -4,(3) ;√13; 2/7; -2/7 ;4intregi 1/3 ;-3 intregi 1/3

Answer 1

8.2⇒p intreaga=8 ; p fractionara 0.2;
-7.2⇒ int=-8 ; fractionara=0.8;
2.(5)⇒ int=2 ; f=0.(5);
-4.(3)⇒ int=5 ; f= 0.(7);
rad din 13⇒ int=3 ; f=(radical din 13)-3;
2/7⇒ int=0 ; f=0,285..;
-2,7⇒ int=0 ; f=0,715...;
