Answer = To find the cost of 20 ml, we need to find the cost per milliliter and then multiply it by 20. Given that 1 litre costs £10.99, we can find the cost per milliliter by dividing the total cost by the number of milliliters in a litre: \[ \text{Cost per milliliter} = \frac{\text{Cost per litre}}{\text{Number of milliliters in a litre}} \] \[ \text{Cost per milliliter} = \frac{£10.99}{1000 \text{ ml}} \] \[ \text{Cost per milliliter} = £0.01099 \] Now, to find the cost of 20 ml, we multiply the cost per milliliter by 20: \[ \text{Cost of 20 ml} = £0.01099 \times 20 \] \[ \text{Cost of 20 ml} = £0.2198 \] So, the cost of 20 ml is £0.2198 or approximately £0.22.
