A) 17/4=4 si 1/4
39/9=4 si 3/9
14/30 = 7/15... nu sunt intregi daca ai gresit si este 30/14=2 si 2/14
A) 6 si 2/3=(6*3+2)/3= 20/3
12 si 1/4=(12*4+1)/4=49/4
2 si 11/12= (2*12+11)/12=35/12

17:4 = 4 (rest 1 ) => 17/4 = 4 intregi si 1/4
39:9 = 4 (rest 3 ) => 39/9 = 4 intregi si 3/4
14:30=0 (rest 14) => 14/30= 0 intregi si 14/30
...=(3*6+2)/3=20/2
