Answer 2

32 muncitori.........50 zile
} i.p.
x muncitori............40 zile

$\frac{x}{32}$= $\frac{50}{40}$

x= $\frac{32\cdot50}{40}$ (facem simplificarea)

x=8·5=40 de muncitori

40 muncitori............40 zile
}i.p.
x muncitori...............64 zile

$\frac{x}{40}$= $\frac{40}{64}$

x= $\frac{40\cdot40}{64}$=5·5=25 muncitori
