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
Don't you mean 17 on a 24 hour clock? That refers to (17-12)= 5:00PM
There cannot be a common ratio for only one number.
Find an equivalent ratio to 3/5.
17/5 or 34/10 or anything equivalent
The equivalent ratio, in its simplest form, is 810/1. You can multiply the numerator and denominator of this ratio by any positive integer to give you an equivalent fraction. 17, for example, gives you 13770/17.
6 to 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
Don't you mean 17 on a 24 hour clock? That refers to (17-12)= 5:00PM
To convert inches to feet, you use the ratio 1 foot = 12 inches. To convert 17 inches to feet, divide 17 by 12. This would be 1 foot and 5 inches.
If x:y is a ratio and p is any non-zero number, then p*x:p*y is an equivalent ratio.
It is: 8 to 10
