$1.00 = £ 0.79<br><br> $12500 US dollars = how many pounds ?<br><br> £350= how many US dollars?
Ivan
For finding the usd to pounds, you will cross multiply. This is just to make it easier to understand. You put the one dollar over the .79. as if it were a fraction, you then put how much usd you have, so in this case 12,500 dollars right next to where you put the one dollar. you obviously don't know how much euro you have so you leave the bottom portion blank. Then you multiply the 12,500 by .79. then divide by 1
