2 [tex]\frac{1}{2}[/tex] inches tall is the same as [tex]\frac{5}{2}[/tex] inches tall.
3 [tex]\frac{1}{3}[/tex] feet tall is the same as [tex]\frac{10}{3}[/tex] feet tall.
If we multiply the actual height by 12, we can convert it to inches:
[tex]\frac{10}{3}[/tex] * [tex]\frac{12}{1}[/tex] = [tex]\frac{120}{3}[/tex] = [tex]\frac{40}{1}[/tex] = 40 inches tall
Divide 40 by [tex]\frac{5}{2}[/tex]. Recall that you multiply by the reciprocal when dividing with fractions:
[tex]\frac{40}{1}[/tex] * [tex]\frac{2}{5}[/tex] = [tex]\frac{80}{5}[/tex] = 16
Therefore, the ratio of the model to the actual statue is 1 : 16.
Hope this helps! :)
