Question

on a trip, you had to change your money from dollars to British pounds. you got 560 pounds for 800 dollars. which is a unit rate that describes the exchange?

Answer 1

1pound is 800/560......which is 80/56-->10/7
so 1 pound is 10/7 dollars....
because you don't say for one dollar it is this many pounds. 
also for unit rate i divide by 560 on both sides to get one pound on one side and then how many dollars on the other
