Macroeconomics HW Question (Exchange Rate): (10 pts!?)?

Question

Here's the problem:

If the exchange rate between the Japanese yen and the U.S. dollar expressed in terms of yen per dollar is ¥110=$1, what is the exchange rate when expressed in terms of dollars per yen?

I always give best answer!!!

Answer 1

divide 1 by 110 and you'll get your answer...which could be rounded off as 0.009 US  = 1 yen
