We are given
two ratios as
First ratio:
[tex]\frac{30}{80}[/tex]
we can simplify it
[tex]\frac{3}{8}[/tex]
Second ratio:
[tex]\frac{12}{32}[/tex]
we can simplify it
[tex]\frac{12}{32}=\frac{4\times 3}{4\times 8}[/tex]
we can cancel 4
[tex]\frac{12}{32}=\frac{ 3}{ 8}[/tex]
so, both ratios are same
so, they are proportional..........Answer
