A two-litre bottle of orange juice is \( \frac{3}{10} \) full. How much orange juice is this?

To find out how much orange juice is in a two-litre bottle that is \( \frac{3}{10} \) full, you can multiply the total volume of the bottle by the fraction that represents how full it is. \[ \text{Amount of orange juice} = \text{Total volume} \times \text{Fraction full} \] Substituting the values: \[ \text{Amount of orange juice} = 2 \, \text{litres} \times \frac{3}{10} \] Calculating this: \[ \text{Amount of orange juice} = 2 \times \frac{3}{10} = \frac{6}{10} = 0.6 \, \text{litres} \] Thus, the amount of orange juice in the bottle is \( 0.6 \) litres.
