one way is to try and cancel out the units so that you are left with the currency you want.
ex:
if you are given 100EUR and want to get USD and are given $1.40/1EUR then you would do 100EUR * $1.40/1EUR = $140 (the EUR cancels). you would divide if you started in USD and wanted to end up with USD. |
