i think basic mapping skills (gradient, aspect, bearing etc) and data interpreting skills,
like out fo the 4 countries shown, which one had a 5% increase in population
or something like that
a good trick for anyone, is we all know that gradient is RISE/RUN well thats what we learnt in maths anyway. but here to get the answer as 1:50 do RUN/RISE it sounds wierd, but it works, you will get a number, and that is the x in 1:x
seriously i tworks, andis much easier than trying to manipulate a fraction
