The farthest distance of two places in an area is 200 km. If someone wants to make a map of that area on a 1 m × 1 m paper, the possible scale to make it is ....
a. 1 : 210
b. 1 : 2.100
c. 1 : 21.000
d. 1 : 210.000

Can you help? The 200 and 210 makes me think that the distance on map won't be an integer.

Firstly, are they decimal points in the answers (b) to (d)?

No. Sorry, forgot that dots represents decimals in international notation. The options are:
a. 1 : 210
b. 1 : 2,100
c. 1 : 21,000
d. 1 : 210,000

OK. Good.
You first need to convert 200km to metres.

Yes, it's 200,000 meters. Now what should I do?

Ok, so you want to represent a length of 200 000 metres on a piece of paper which is 1 metre wide.

How do you need to scale it down, so that it will fit on the page (and leave a bit of a margin)?

Correct! You want to divide all real measurements by a bit more that 200 000 so it'll fit on the paper. Can you see why?

So that we have some little spaces to labels both ends of the line?
