Marinada '22

[lang=hr] Svi znamo da je Trnoružica uvijek umorna. U borbi da ostane budna povremeno joj pomaže šalica kave.\\ Jednog je jutra najprije popila pola šalice crne kave. Dopunila je šalicu mlijekom i popila trećinu šalice napitka. Ponovno je ulila mlijeko do vrha, popila šestinu šalice i treći je put dopunila mlijekom. Konačno, popila je cijelu šalicu napitka.\\ Koliko je mlijeka, mjereći prema veličini šalice, ukupno popila Trnoružica? Rješenje upiši u obliku decimalnog broja zaokruženog na dvije decimale. Primjerice, ako je popila $\frac{1}{3}$ šalice mlijeka, upiši $0.33$. [/lang] \\ \\ [lang=en] We all know that Sleeping Beauty is always tired. Occasionally, a cup of coffee helps her fight sleepiness.\\ One morning she drank half a cup of black coffee. Then she filled it back up with milk and drank one third of the beverage. Once again she poured milk in the cup, drank one sixth of the mixture and refilled it with milk for the last time. Finally, she drank the whole cup.\\ How much milk, in comparison to the cup, did Sleeping Beauty drink? The solution is a decimal number rounded to two decimal places. For example, if she drank $\frac{1}{3}$ of the cup of milk, write $0.33$. [/lang]
