Answer 1

Equivalent ratios are those ratios which are same that is on simplifying each of them, we will get the same answer.

A.$\frac{2}{3} and \frac{9}{15} = \frac{3}{5}$

So they are not equivalent

B.$\frac{5}{8} and \frac{15}{21} = \frac{5}{7}$

So they are not equivalent

C.$\frac{3}{12} and \frac{6}{18} = \frac{1}{4} and \frac{1}{3}$

They are not equivalent too.

D.$\frac{4}{10} and \frac{12}{30} = \frac{2}{5} and \frac{2}{5}$

And they are equivalent. SO the correct option is D .
