Answer :
See explanation below
Explanation:Proportion simply means two ratios or two fractions are equal.
For example:
1/5 is proportional to 2/10
[tex]\frac{1}{5}=\frac{2}{10}[/tex]This is because when we break down 2/10 to the simplest term, we would have 1/5
In proportion, the difference between the two fractions that are equal to each other is that one fraction was multiplied by a constant number in both the nummerator and denominator.
using the example above:
[tex]\begin{gathered} \frac{2}{10}=\frac{2(1)}{2(5)} \\ =\text{ }\frac{2}{2}\times\frac{1}{5} \\ =\text{ }\frac{1}{5} \end{gathered}[/tex]Another example of proportion:
3/4 = 9/12
9/12 = 3(3)/3(4) = 3/4
