A large jug can hold 4.5 litres of milk. A smaller jug can hold 0.8 litres. How many small jugs can be filled completely from the large jug and how much milk will be left in the large jug? Show calculations.

Step-by-step solution

1. Step 1: Compute how many times 0.8 litres fits into 4.5 litres using integer division.
2. Step 2: $4.5÷0.8=5.625$
3. Step 3: Take only the whole number part, which is 5, as each small jug must be completely filled.
4. Step 4: Compute the volume used by these 5 jugs: $5\times 0.8=4.0$ litres.
5. Step 5: Subtract the used volume from the large jug’s capacity to find the remainder: $4.5-4.0=0.5$ litres.
6. Step 6: Hence 5 small jugs can be filled and 0.5 litres of milk remain in the large jug.
