Amber spent a day with a design engineer. A blueprint that the engineer was working on uses a scale of 3:200. If the room dimensions are 10 m by 3 m, what lengths would be drawn on the blueprint in the centimetres?
--I know the answer is 15 cm by 4.5 cm, but could someone explain how to get that?
THANKS:)

3cm : 200cm (2 metres)
so, for every 200cm in reality we have 3cm on the blueprint.
Room length is 10 m = 1000cm => 1000/200 = 5......so, 5 x 3cm = 15cm
Room width is 3 m = 300cm => 300/200 = 1.5......so, 1.5 x 3cm = 4.5cm
