Answer:
18:54
Step-by-step explanation:
We have to simplify these ratios.
If the most simplified form of the ratios are equal, they are equivalent
3:9
[tex]r = \frac{3}{9} = \frac{1}{3}[/tex]
24:54
[tex]r = \frac{24}{54} = \frac{12}{27} = \frac{4}{9}[/tex]
18:54
[tex]r = \frac{18}{54} = \frac{9}{27} = \frac{3}{9} = \frac{1}{3}[/tex]
Same ratio as 3:9, so 18:54 is equivalent to 3:9
36:81
[tex]r = \frac{36}{81} = \frac{12}{27} = \frac{4}{9}[/tex]
