For the model, every 2 feet would equal 3 inches or every foot would equal 1.5 inches.
You can divide to see how many 2 feet are in 14 feet.
[tex]14 \div 2 = 7[/tex]
Since there are 7, you can multiply by 3 to see how many inches the model is.
[tex]7 \times 3 = 21[/tex]
The train model is 21 inches tall.
