Based on the calculations, the ratio 28:40 is proportional to the ratio 7:10.
What is ratio?
Ratio can be defined as a mathematical expression that is typically used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.
In this exercise, we would determine a ratio that is proportional to the given ratio by dividing it in simplest form as follows. Thus, we would divide both sides by 4:
[tex]28:40 = \frac{28}{4} :\frac{40}{4} =7:10[/tex]
