Assuming the scale is 750:1, you can set up the following proportion:
[tex] \frac{301}{x} = \frac{750}{1} [/tex]
Cross multiply the values.
750x = 301
Divide both sides by 750 to solve for x.
x = [tex] \frac{301}{750} [/tex]
Converted to a decimal and rounded to the nearest tenth, the scale model will be 0.4 meters tall.
