Please help me to solve this.

Question

a). Convert $1 from U.S. dollars to euros to pounds to yen.

b). Convert $1 directly (in one step) from U.S. dollars to yen.

c). Are answers from parts a and b exactly equal? If not, what could account for the differences in the results?

d). Take the reciprocal of 122.63 Japanese yen. What is the result, and what does it mean?

e). Convert 10 U.S. dollars to euros in three ways: by scaling; by using the conversion factor 1 USD =_____ euro; and by using the reciprocal of the conversion factor 1 euro = _____ USD.

Answer 1

I would suggest two notions:

1) supply the conversion rates oanda.com or xe.com

2) it is helpful to know which currency is worth more in terms of a one to one basis.

for instance 1 USD = slightly less than 1 EUR.

1 EUR = 1.1067 USD.

when you multiply or divide by the conversion factor your answer should make sense.
