Question

Imi puteti spune dacă 4 robinete umplu un bazin in 5 ore in cate ore umple un bazin 6 robinete

Answer 1

$4 \: robinete \: ..... \: 5 \: ore \\ 6 \: robinete \: ..... \: x \: ore$

$\frac{4}{6} = \frac{x}{5}$

$x = \frac{4 \times 5}{6} = \frac{20}{6} = \frac{10}{3} = 3.(3) \: (3 \: ore \: si \: ceva)$

4 r ............... 5 h 

6 r ................x h

x = 4 x 5 : 6 = 20 : 6 = 3, (3) h = 3 ore 20 minute
