Answer 1

Ai răspuns pe foaie.

Answer 2

a, b, c i.p {0,(3); 0,5; 0,25}
0,(3)=3/9=1/3
0,5=5/10=1/2
0,25=25/100=1/4
a/3=b/2=c/4
a=3b/2
c=4b/2=2b
6*3b/2+2b-5*2b=50
9b+2b-10b=50
b=50=>a=3*50/2=75, c=2*50=100

sau
a/3=b/2=c/4=k
a=3k, b=2k și c=4k
6*3k+2*2k-5*4k=50
18k+4k-20k=50
2k=50 |:2
k=25=>a=75, b=50, c=100
