which server is this ???????

Answer 2

(10 Aus) x (1 NZ / 0.8262 Aus) x (1 Brit / 3.1517 NZ) x (1 US$ / 0.6536 Brit) =

(10) / (0.8262 x 3.1517 x 0.6536) = US$ 5.87 (rounded)

Notice that each of the underlined fractions in the top line is equal to " 1 ".
So they change the units of the " 10 AUS " but they don't change its value.,
