Solution

Part 1) We have been given the following information

$1 = 1,100 Won ----------------- 1

$1 = 0.70 Pound ---------------- 2

1 Won = (1/1,000) $ = 0.0009 $

1 Pound = (1/0.70) $ = 1.43 $

Replacing the value of 2 in 1 we get the following

0.70 Pound = 1,100 Won

By dividing we will get the value of one pound in terms of Won

1 Pound = (1,100/0.70) Won

1 Pound = 1,571.43 Won

Or

1 Won = (0.70/1,100) Pound = 0.000636 Pound

Part 2) We have been given the following information

$1 = 1,000 Won --------------------- 3

$1 = 0.80 Pound ---------------------- 4

Replacing the value of 4 in 3 we get the following

0.80 Pound = 1,000 Won

By dividing we will get the value of one pound in terms of Won

1 Pound = (1,000/0.80) Won

1 Pound = 1,250 Won

Or

1 Won = (0.80/1000) Pound = 0.0008 Pound

1 Won = (1/1000) $ = 0.001 $

1 Pound = (1/0.80) $ = 1.25 $
