Question

8 muncitori executa o lucrare in 12zile dar 6 muncitori in cate zile?

Answer 1

Folosim regula de 3 simpla:

8 muncitori ..... 12 zile
6 muncitori .....  x zile

$\frac{8}{6} = \frac{12}{x}$
=> 8x = 6$=> x = \frac{72}{8}$ => x = 9 zile

Answer 2

8 muncitori---------------------------12 zile
6 muncitori ---------------------------- x zile
8/6= x/ 12
6x=8*12
6x=96
x=16 zile
