Answer :

Certainly! Let's solve the problem step-by-step:

We are given that a bucket can hold 5 litres of water, and we are asked how many half litres of water are required to fill the bucket.

1. Define the total capacity of the bucket: The bucket can hold 5 litres of water in total.

2. Understand the question's requirement: We need to find out how many half litres of water are needed to fill the bucket to its full capacity.

3. Determine the volume of a half litre: One half litre is equivalent to 0.5 litres.

4. Calculate the number of half litres needed:
- We will divide the total capacity of the bucket (5 litres) by the volume of one half litre (0.5 litres).
- So, we calculate [tex]\( \frac{5 \text{ litres}}{0.5 \text{ litres/half litre}} \)[/tex].

5. Perform the division:
- [tex]\( 5 \div 0.5 = 10 \)[/tex]

Therefore, you need 10 half litres of water to fill the bucket to its full capacity of 5 litres.

So the final answer is:
10 half litres.
