A model uses scale 1:25. A door is 8 centimetres high on the model. What is its real height? Enter the number of metres.
Correct answer
2
Explanation
The real height is 8 times 25, or 200 centimetres, which equals 2 metres. Reporting 200 as metres would skip the centimetre-to-metre conversion and make the door one hundred times too tall.
