A grocery store is selling individual bottles of water, and each bottle contains 750 millilitres of water. If 12 bottles are purchased, what conversion will correctly determine how many litres that customer will take home?

To determine how many litres are contained in 12 bottles of water, we first need to calculate the total volume of water in millilitres and then convert that volume into litres.

Each bottle contains 750 millilitres, so if a customer purchases 12 bottles, the total volume in millilitres is calculated as follows:

Total volume in millilitres = Number of bottles × Volume per bottle = 12 × 750 = 9,000 millilitres.

Now, to convert millilitres to litres, it's essential to understand the relationship between these two units of measurement. Since 1 litre is equivalent to 1,000 millilitres, we can find out how many litres are present in 9,000 millilitres by dividing the total volume in millilitres by 1,000:

Volume in litres = Total volume in millilitres ÷ 1,000 = 9,000 ÷ 1,000 = 9 litres.

The correct conversion factor was identified correctly, which states that 1,000 millilitres equals 1 litre. This fundamental relationship allows us to easily convert between millilitres and litres, confirming that knowing the equivalence of these two units is crucial for performing
