since the pools are similar each to other, then we can write these proportions: \[\Large \begin{gathered} 14:7 = 22:b \hfill \\ \hfill \\ 14:7 = 16:c \hfill \\ \hfill \\ 14:7 = a:9 \hfill \\ \end{gathered} \]

If I apply the fundamental property of proportions, I can write: \[\Large b = \frac{{22 \times 7}}{{14}} = ...?\]

hint: \[\Large b = \frac{{22 \times 7}}{{14}} = \frac{{154}}{{14}} = ...?\]
Michele_Laino
  • Michele_Laino
what is 154: 14 =...?
anonymous
  • anonymous
is it 9 @Michele_Laino I got disconnected sorry
Michele_Laino
  • Michele_Laino
hint: 154:14 = 11 right?
anonymous
  • anonymous
because of 22 right?
Michele_Laino
  • Michele_Laino
yes!
Michele_Laino
  • Michele_Laino
so, we have: b=11
jennyrlz
  • jennyrlz
Just wondering why did you get b=22*7/14 instead of 22*87/14b?
anonymous
  • anonymous
oh ok so is that partially the answer
Michele_Laino
  • Michele_Laino
since the pool for dog is scaled by a factor 1/2 with respect to the other pool, so b has to be 22/2=11
