5

Answer 1

0,3=3/10
2 intregi 1/5 = (2x5+1)/5 = 11/5
(3/10 + 2/5) + (5 - 11/5)=
(3+4)/10 + (25-11)/5 =
7/10 + 14/5 =
(7+28)/10=
35/10 =
7/2 =
3 intregi 1/2

Answer 2

(0,3+2/5)+[5-(2x5+1)/5]=
= (3/10+2/5)+(5-11/5)
= ( 3/10+4:10)+(25/5-11/5)
= 7/10+14/5
= 7/10+28/10
= 35/10
= 7/2

Sper ca te-am ajutat ! :)
