Efectuați a 7/3 + 4/3; b 4/5 + 9/5 c 12/7 + 3/7; d 7/9 + 25/9 e 4/3 20 + 28/3; f 13/5 + 6/5​

Answer 1

Răspuns:

a) 7/3 + 4/3 = (7 + 4)/3 = 11/3 = 3 intregi 2/3;

b) 4/5 + 9/5 = (4 + 9)/5 = 13/5 = 2 intregi 3/5

c) 12/7 + 3/7 = (12 + 3)/7 = 15/7 = 2 intregi 1/7;

d) 7/9 + 25/9 = (7 + 25)/9 = 32/9 = 3 intregi 5/9;

e) 4/3 + 28/3 = (4 + 28)/3 = 32/3 = 10 intregi 2/3;

f) 13/5 + 6/5 = (13 + 6)/5 = 19/5 = 3 intregi 4/5 ​
