Question

aflati a ,b , c stiind ca sunt direct proportionale cu 0,5 ; 0,2 ; 0,(3) si a+b+c=930

Answer 1

a=0,5k  b=0,2k   c=o,(3)k   a=1|2k  b=1|5k  c=1|3k   1\2k+1|5k+1|3k=930  k=90   a=90|2  b=90|5   c=90|3=30

Answer 2

A=0.5 k=5/10=1/2    b=0,2k=2/10=1/5  c=0,(3)=3/9=1/3          1/2k+1/5k+1/3k=390
