Answer

Explanation:

Step1: Identify conversion rate

We know 1.2 AUD = 1 USD, so 1 USD = $\frac{1}{1.2}$ AUD. To convert from AUD to USD, we multiply the amount in AUD by the conversion - factor of $\frac{1\ USD}{1.2\ AUD}$.

Step2: Apply conversion to 22 AUD

To convert 22 AUD to USD, we use the expression $22\ AUD\times\frac{1\ USD}{1.2\ AUD}$.

Answer:

$22\ AUD\times\frac{1\ USD}{1.2\ AUD}$ (the second option)
