Question

Rezolvați ecuatia [1, (3)x/2 - 2 și 1/4 ] : 0,6 = x/9 x€Q

Answer 1

1,(3)=13-1/2=12/9 care se simplifica cu 3=4/3
2 si 1/4=2×4+1/4=8+1/4=9/4
0,6=6/10 care se simplifica cu 2=3/5
acum execitiul devine

(4x/3/2 - 9/4):3/5=x/9
(4x/3 ori 1/2-9/4) ori 5/3=x/9
(4x/6-9/4) ori 5/3=x/9
4x/6 ori 5/3- 9/4 ori 5/3=x/9
20x/18-45/12=x/9
20x/18-x/9=45/12
20x/18-2x/18=45/12
18x/18=45/12 
x=45/12
