Task B-1.4. Three friends got hungry after a strenuous training session. Marko brought three identical pastries, Ante brought four, and Luka forgot to bring his in a hurry. However, the friends evenly distributed the pastries and ate them all. Luka didn't want to owe his friends anything, so he took out seven kuna and said to divide the money fairly. How many kuna did Marko get, and how many did Ante get?
Solution. There were a total of 7 pastries, and each of the three friends received $2 \frac{1}{3}=\frac{7}{3}$ pastries.

(1 point)

Marko ate his $\frac{7}{3}$ pastries and gave Luka $\frac{2}{3}$ of a pastry, while Ante, after eating his share, gave Luka $\frac{5}{3}$ of a pastry.

(1 point)

Therefore, the money must be divided in the ratio 2 : 5, so Marko gets 2 kuna, and Ante gets 5 kuna.
