Question

A model is made it an Airbus A300 aeroplane. The length of the model is 36cm. The length of the real aeroplane is 54cm. Find the ratio of the length of the model to the length of the real aeroplane. Give your answer in the ratio form 1:n

Answer 1

Answer: 1 : 150

Step-by-step explanation:

The length of the model is 36cm. The length of the real aeroplane is 54 cm. This length seems implausible as it is of the real plane so I will assume that you meant to type 54m.

First convert 54 m to centimetres:

1 m = 100cm

= 54 * 100

= 5,400 cm

Length of model : length of plane

36 : 5,400

Divide both sides by 36:

= 1 : 150

Answer 2

The ratio of the length of the model to the length of the real aeroplane is 1 : 150

Calculation:

First, convert 54 m to centimeters:

1 m = 100cm

= 54 ( 100)

= 5,400 cm

Now

Length of model : length of plane

36 : 5,400

= 1 : 150
