Question

Trei muncitori au primit impreuna pt o lucrare suma de 930 lei.Cat a primit fiecare muncitor stiind ca numele lor sunt invers proportional cu 2,3,5

Answer 1

{a,b,c}--->{2,3,5}(I.P)
2a=3b=5c|:30
$\frac{a}{15} = \frac{b}{10} = \frac{c}{6 }=k \\ a=15k,b=10k,c=6k$
31k=930
k=30
a=450, b=300, c=180
