It is: 5/12 reduced
15/12 = 5/4
To 2/15
four fifths

No, 12 to 15 and 4 to 5 are not equal. To determine if two ratios are equal, you need to simplify them to their simplest form. In this case, 12 to 15 simplifies to 4 to 5, so they are equal. However, 4 to 5 cannot be further simplified, so it is not equal to 12 to 15.
3/5 = 9/15 and is not equal to 12/15
11/15 is.
-3 + 15 = 12
3 - negative 15 equal too = -12
