I NEED HELP WITH NUMBER 4

Answer:
4.5 inches
Step-by-step explanation:
To find the height in inches of the model, you need to change the ration into a fraction:
[tex]\frac{1}{50}[/tex]
Then try to figure out the value of the denominator in terms of the ratio:
[tex]\frac{1}{50} =\frac{x}{725}[/tex]
In this equation we need to figure out how much the denominator of the fraction is changing by, by dividing 725 by 50. Then, multiply that by one:
[tex]4.5[/tex]
