Well for a starters the exchange rate is not realistic anymore and I though DVDs were cheaper in the US anyway... unless it is maybe a box set? Personally I would just go for long division... divide 299.9 by 19 but you could be at it for a while... it's not exact... does it say how close you need to get... number of DP? Â£15.78...

For CSSE Maths, I think it is apprxmt. 1 minute a question. Hence wanted to know, if there were faster ways of doing this. The question paper which we were looking at wanted the answer in 2 decimals.

The question paper which we were looking at wanted the answer in 2 decimals. maybe an estimate... 29.99 approx \$30 1.9 approx 2 \$/Â£ answer Â£15 But 2dp suggests it's got to be division...
