Answer

Explanation:

Step1: Identify conversion rate

Given 1.2 AUD = 1 USD, so the conversion - factor is $\frac{1\ USD}{1.2\ AUD}$.

Step2: Convert 22 AUD

To convert 22 AUD to USD, we multiply 22 AUD by the conversion - factor. The expression is $22\ AUD\times\frac{1\ USD}{1.2\ AUD}$.

Answer:

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