Using proportions, the expression that can be used to convert 22 Australian dollars to US dollars is:
22 AUD x (1 USD/1.2 AUD).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
In this problem, we have that 1.2 Australian dollars equals 1 US dollar, and we want to find the value of 22 Australian dollars, hence we can use the following <em>rule of three</em>.
1.2 AUD - 1 USD.
22 AUD - x USD
Applying cross multiplication:
1.2x = 22
x = 22 x 1/1.2.
Hence the expression that can be used to convert 22 Australian dollars to US dollars is:
22 AUD x (1 USD/1.2 AUD).
