Question

Exercitul 40 plz. Dau coroana

Answer 1

a+b+c=1
a/0,1=b/0,4=c/0.(3)=(a+b+c)/(0,1+0,4+0,(3))= 1/(0,5+0,(3))=1/(1/2+1/3)=1/(5/6)
 
                                 =6/5


a/0,1=6/5............⇒. a=0,1*6/5=0,1*1,2=0.12

b/0,4=1,2  ..............⇒.b=0,4*1,2=0,48
c= 1-0,12-0,48=1-0,6=0,4



verificare
c/(1/3)=6/5 ....c= (1/3) *(6/5)=2/5=0,4   
bine rezolvat
