Answer 1

the answer is D

Explanation:

Answer 2

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

A.
`(2)/(3) and (9)/(15) = (3)/(5)`

So they are not equivalent

B.
`(5)/(8) and (15)/(21) = (5)/(7)`

So they are not equivalent

C.
`(3)/(12) and (6)/(18) = (1)/(4) and (1)/(3)`

They are not equivalent too.

D.
`(4)/(10) and (12)/(30) = (2)/(5) and (2)/(5)`

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