Avi has a jar of capacity 2 litres. A quarter of it is filled with water. How much water is there in the jar?

Answer

To find out how much water is in Avi's jar, we start with the total capacity of the jar, which is 2 litres. A quarter of the jar is filled with water. To calculate a quarter of 2 litres, we can use the following steps: 1. Determine a quarter in numerical form: A quarter means 1/4. 2. Multiply the total capacity by the fraction: \( \text{Amount of water} = \text{Total capacity} \times \frac{1}{4} \) \( \text{Amount of water} = 2 \text{ litres} \times \frac{1}{4} = \frac{2}{4} \text{ litres} = 0.5 \text{ litres} \) 3. Convert litres to millilitres: We know that 1 litre is equivalent to 1000 millilitres. Therefore, 0.5 litres is equal to: \( 0.5 \text{ litres} = 0.5 \times 1000 \text{ ml} = 500 \text{ ml} \) Hence, there are 500 ml of water in the jar. The correct answer is A: 500 ml.
