## Task 1 - 230621

From a dairy farm, 2200 crates each containing 25 containers of $\frac{1}{4}$ liter of milk, 600 crates each containing 24 bottles of $\frac{1}{2}$ liter, and 800 crates each containing 12 bags of 1 liter of milk are to be delivered in one day.

The total amount of milk required for this was delivered in tankers, each of which can hold 9000 liters of milk.

a) Calculate the total amount of milk in liters that is to be delivered on this day!

b) Calculate the smallest possible number of tankers that were sufficient for the delivery of the required amount of milk!
a) Because $2200 \cdot 25: 4=13750, 600 \cdot 24: 2=7200, 800 \cdot 12 \cdot 1=9600$ and $13750+7200+9600=30550$, a total of 30550 liters of milk should be delivered.

b) Because $30550: 9000=3$ remainder 3550, four tankers were sufficient for the transport of 30550 liters of milk, but not fewer. Therefore, 4 is the smallest possible number.
