I was looking at one of the Maths questions with my daughter. The question is
Gretchen pays $29.99 for a DVD on her holiday. The exchange rate is Â£1=$1.90. How much was DVD in pounds?
What is the best way to do this question in shortest possible time?
Thanks for the help !!
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?
