Simple Example

Quick Example

Imagine you have a 1-liter bottle of your favorite juice. If you pour out exactly one-fourth of that juice, the amount you poured is a quarter liter. So, a 1-liter bottle can fill four glasses, each holding a quarter liter.

Worked Example

Step-by-Step

Let's say a chai shop owner wants to measure out a quarter liter of milk for a small batch of chai.
---Step 1: The owner knows a full liter is 1000 milliliters (ml).
---Step 2: A quarter (1/4) means dividing the total into 4 equal parts.
---Step 3: So, the owner needs to calculate 1000 ml divided by 4.
---Step 4: 1000 ml / 4 = 250 ml.
---Answer: Therefore, a quarter liter of milk is 250 ml.
