whatttttttt? i have no idea what that is
0.71 x 22 is the expression that works, because 1 AUD = 0.71USD.
1/4 + 1/4 = 1/2
I got 1/2 because if you add 1/4 and 1/4 you'd get 2/4, and when you simplify 2/4 you'd get 1/2.

Although you did not include units, I just used centimeters.
However, if there were no units, then just put your answer.
