The question is an illustration of ratios and proportions
The Bospolder fox is 28 inches tall at the shoulder,
Represent the ratio as:
[tex]Scale = Shoulder : Tail[/tex]
For the red fox, we have:
[tex]Red = 20in : 55in[/tex]
For the Bospolder fox, we have:
[tex]Bospolder =Shoulder : Tail[/tex]
To calculate the length of the shoulder of the Bospolder fox, we need its length at the tail.
Since it is not given, I will make an assumption.
Assume, the Bospolder fox is 77in tall at the tail.
The ratio becomes
[tex]Bospolder =Shoulder : 77in[/tex]
Both animals are proportional; this means that they have the same ratio.
So, we have:
[tex]Shoulder : 77in = 20in : 55in[/tex]
Express as fraction
[tex]\frac{Shoulder }{ 77in }= \frac{20in }{55in}[/tex]
Multiply both sides by 77in
[tex]Shoulder = \frac{20in }{55in} \times 77in[/tex]
[tex]Shoulder = \frac{20in \times 77}{55}[/tex]
[tex]Shoulder = 28in[/tex]
Using the assumed length, the Bospolder fox is 28 inches tall at the shoulder,
