Sorry, the solution is available only in Hungarian. Google translation

Megoldás: 73 tyúk 1 tucat tojást tojik 1 nap alatt, tehát 1 tyúk 1 nap alatt $\frac{1}{73}$ tucat tojást tojik. 37 tyúk 1 nap alatt 1 kg búzát eszik meg, tehát 1 tyúk 1 nap alatt $\frac{1}{37}$ kg búzát eszik meg. Tehát $\frac{1}{73}$ tucat tojás előállításához kell $\frac{1}{37}$ kg búza, így egy tucat tojás előállításához ennek 73-szorosa, azaz $\frac{73}{37}$ kg búza.
