Currency conversion

Please show me the maths to work out how to convert $170k usd to GBP when the rate of the GBP is 1.29 and also 1.21.
I am getting algorithims mixed up and I cannot decide if I should divide or multiply by a daily given exchange rate.
Exchange costs should be ignored.

Divide $ by the 1.29 to get pounds. Multiply £ by 1.29 to get $

Again thank you

The 1.29 and 1.21 rates may be for buying and selling - banks rarely do anything for nothing,

Go into a bank and ask for $170 and they will likely charge you £140.49 ($170/1.21)

Take the $170 back into the bank a few minutes later and ask them to exchange it for sterling and they will likely give you £131.78 ($170/1.29)

My last iPhone update added a conversion button to the calculator. Lets you convert volumes, weights, measures etc including currency. I pick the two currencies I want to play with and put the amount in one and like magic the other is filled out at the same time. While it doesn't factor in any charges the bank or credit card company will charge for the transaction it is close enough for most of what I'll do.

If you have a windows browser ( others may also do it ) type in the address bar convert 170 usd to gbp. This will also work for other conversions e.g. weights.
