Klaus replies: "In total, 15000 dt of potatoes were harvested. $\frac{1}{5}$ of this amount was collected by us students, $\frac{1}{3}$ of this amount was harvested by some cooperative farmers with the potato combine, and the rest was collected by the other cooperative farmers."

How many decitons of potatoes were harvested by

a) the students?

b) the farmers with the potato combine?

c) the remaining cooperative farmers?
a) The students collected $\frac{1}{5} \cdot 15000 \mathrm{dt}=3000 \mathrm{dt}$ of potatoes.

b) The farmers with the potato combine collected $\frac{1}{3} \cdot 15000 \mathrm{dt}=5000 \mathrm{dt}$ of potatoes.

c) The remainder is $15000-3000-5000=7000 \mathrm{dt}$.
