No, it is not equivalent. Think of it this way. If you had £12 and I had £5 then you would have money in the ratio of 12 to 5 compared to me. If you then only had £5 and I had £17 (which represents the new ratio of 5 to 17) you would not agree that this was equivalent as a proportion (you would rightly feel that you had lost out)!
6 to 5
It is: 12/20 = 3/5
It is 12:1
Find an equivalent ratio to 3/5.

6 to 5
12 to 10
It is: 12/20 = 3/5
-5
If you mean 30/12 then it is 5/2 in its simplest form
If x:y is a ratio and p is any non-zero number, then p*x:p*y is an equivalent ratio.
It is 12:1
To determine if 2 to 5 is equivalent to 12 to 30, we need to simplify both ratios by finding their greatest common factor. For the first ratio, the greatest common factor of 2 and 5 is 1, so it remains 2 to 5. For the second ratio, the greatest common factor of 12 and 30 is 6, so when simplified, it becomes 2 to 5 as well. Therefore, yes, 2 to 5 is equivalent to 12 to 30.
120 to 180 is an equivalent ratio.
There are infinitely many equivalent ratios to 15:5, eg 12:4, 30:10, 45:15, 60:20 The simplest form of the ratio is 15:5 = (3×5):(1×5) = 3:1
