How many 250 ml cups can be filled from a 2 litre bottle?
The correct answer and explanation is:
Correct Answer:
You can fill 8 cups of 250 ml from a 2-litre bottle.
Explanation (Approximately 300 Words):
To determine how many 250 ml cups can be filled from a 2-litre bottle, we first need to understand the relationship between millilitres (ml) and litres (L).
Basic conversions:
- 1 litre (L) = 1,000 millilitres (ml)
So, a 2-litre bottle contains: 2 L×1,000 ml/L=2,000 ml2 \text{ L} \times 1,000 \text{ ml/L} = 2,000 \text{ ml}
Now, each cup holds 250 ml.
To find out how many of these cups can be filled from 2,000 ml, we divide: 2,000 ml÷250 ml=82,000 \text{ ml} \div 250 \text{ ml} = 8
This means you can pour exactly 8 full cups of 250 ml from a 2-litre bottle.
Additional Clarification:
It’s important to recognize that only full cups are counted here. Each cup must be filled to 250 ml to be considered complete. If there were any leftover amount less than 250 ml, it wouldn’t count as a full cup.
Let’s suppose the bottle contained a different volume, say 2.1 litres (2,100 ml). Then: 2,100÷250=8.42,100 \div 250 = 8.4
This result means you could fill 8 full cups, and there would be 0.4 of a cup (or 100 ml) remaining, which is not a full 250 ml cup.
In our original case of a 2-litre bottle, the division results in a whole number, meaning the volume divides evenly without any remainder: 2,000÷250=8.02,000 \div 250 = 8.0
So, you get exactly eight full cups, and no liquid is left over.
This straightforward division highlights the practical utility of unit conversions in everyday tasks like measuring drinks, cooking, or distributing liquid portions evenly.
