In 3 metres there are 300 centimetres. Each centimetre on the scale is 300 centimeters, or a ratio of 1:300. The tree is 5 centimetres on the scale. Each centimeter on the scale is 300 centimetres, therefore 5 centimetres on the scale is 1500 centimetres. 1500 centimetres is equal to 15 metres.
The answer will be 4.9. =)
Since we know 1 metre is 0.01 dekametres, we can use this to answer the question!
We simply multiply 490 by 0.01. =)
