Question: 1
The donkey asked 500 millilitres of kheer? Isn’t that more than a litre?
Answer: No, 500 millilitre of kheer is less than a litre, it is half litre.
The fox said – Come on, don’t behave like a donkey! One litre is equal to 1000 millilitres, so 500 millilitres is half a litre.
Question: 2
The donkey looked confused and asked – Ten glasses of 100 ml each. How much is that?
Answer: Quantity of kheer in a glass = 100 mL
Quantity of kheer in 10 glasses = 10 × 100 mL
= 1000 mL
We know that,
1000 mL = 1 litre
Hence, 10 times 100 mL = 1 litre
Question: 3
Each ant drinks 1 millilitre of kheer.
So, 1000 ants drink: 1000 × 1 mL = _______ mL
Answer: Given that each ant drinks 1 millilitre of kheer.
So, 1000 ants drink = 1000 × 1 mL = 1000 mL
Therefore 1000 ants drink 1000 mL of kheer, i.e., 1 litre of kheer
