You can set up a proportion like this, where the smaller figure is represented in the numerator, the larger figure in the denominator, and each fraction represents the similar relationship between them in different forms:
[tex] \frac{48}{75} = \frac{4}{x} [/tex]
Solve for x using cross-multiplication:
[tex]48x = 300 \\ x = 6.25[/tex]
The corresponding side of the larger figure is 6.25 inches long.
