To convert Australian dollars (AUD) to US dollars (USD), you want to use a conversion factor that expresses the relationship between the two currencies.
Given that 1.2 Australian dollars equals 1 US dollar, you want to express this as a fraction that will convert AUD to USD.
To convert from AUD to USD, you should use the fraction that shows how many US dollars is equal to a given amount of Australian dollars.
The correct expression would be:
\[ 22 \text{ AUD} \times \frac{1 \text{ USD}}{1.2 \text{ AUD}} \]
This option is represented as:
\[ 22 \text{ AUD} \times \text{StartFraction 1 \text{ USD} Over 1.2 \text{ AUD} EndFraction} \]
This means you are taking 22 AUD, and for every 1.2 AUD, you are getting 1 USD, thereby converting AUD to USD.
Thus, the correct option is:
\[ 22 \text{ AUD} \times \frac{1 \text{ USD}}{1.2 \text{ AUD}} \]
